Birla Trimaya Devanahalli — 1, 2, 3 & 4 BHK Township Near Bangalore Airport

Published: 3 June 2026 | By L K Monu Borkala, Senior Property Advisor, OneCity Property — 20 years in Bangalore real estate

Birla Trimaya is the most significant township launch in Devanahalli in the past decade — 52 acres of land, 2,600+ homes across four RERA-registered phases, and a location 2 kilometres before Kempegowda International Airport on Shettigere Road. Phase 1 (550 apartments) sold out within three days of launch in September 2023, which is one of the strongest demand validation signals any Bangalore new launch has produced in recent memory. Phase 4 received RERA approval in January 2026, meaning Birla Trimaya is actively selling across multiple phases simultaneously in mid-2026.

This guide covers what 52 acres of Birla Estates township actually delivers, the four-phase RERA structure and what it means for buyers, the Devanahalli–Airport corridor fundamentals, the honest pricing analysis across configurations, and the investment case for a township that has already validated its demand with Phase 1's three-day sellout.

The Phase 1 Sellout in Three Days: What It Tells You About Birla Trimaya

When a 550-unit Phase 1 sells out in three days, two things are simultaneously true: the pricing was either very sharp relative to competing launches at the time, or the Birla brand in Devanahalli generated a level of buyer confidence that overwhelmed supply. In Birla Trimaya's case, both were true in September 2023.

Devanahalli in September 2023 was at the early part of its current appreciation cycle. The Airport Metro line (Blue Line Phase 2B) had just had its alignment confirmed. The KIADB Aerospace Park was beginning to attract global aerospace employers. And Birla Estates — fresh from its successful launches in Birla Alokya (Whitefield) — brought a 52-acre township to a corridor where no branded developer had attempted that scale before. The combination of Birla brand, airport proximity, metro alignment and competitive pricing produced the three-day sellout. Phase 2, 3 and 4 have each registered progressively higher prices as the corridor matures, confirming that the early Phase 1 buyers received the best entry point.

For buyers evaluating Birla Trimaya in 2026, the Phase 1 sellout is context, not a buying trigger. Phase 4 is now live at materially higher prices. The relevant question is whether Phase 4 pricing — approximately ₹1.12 Crores for a 1 BHK and ₹2.50+ Crores for a 3 BHK — still represents value in the 2026 Devanahalli corridor. Read our area-wise Bangalore price guide for the full corridor context.

Devanahalli–Airport Corridor: Why This Location Works in 2026

Devanahalli's residential market is anchored by three fundamentals that have each strengthened since 2023. First, the KIADB Aerospace Park's employment density has grown — Boeing India, Airbus Technology Centre, Shell R&D Campus and multiple Tier 1 aerospace suppliers now have operational headcount in the zone. Second, the NH-44 (Bellary Road) signal-free corridor from Hebbal to Devanahalli has improved travel times to Manyata Tech Park and Hebbal to approximately 25–35 minutes. Third, the Blue Line Metro Phase 2B (Doddajala station, 2.5 km from Birla Trimaya) is under active construction and expected operational by 2027–2028.

The airport adjacency at 2 kilometres is genuinely significant for frequent flyers, NRIs and aerospace professionals. No other residential township in Bangalore proper offers this proximity to an international airport hub. The flip side — which honest advisory requires acknowledging — is that established social infrastructure (international schools, multi-specialty hospitals, established retail) is thinner at Shettigere Road than at Yelahanka, Hebbal or Whitefield. Families with school-going children in 2026 will be driving 15–20 minutes for most school options. Verify actual distances before committing rather than relying on proximity claims in marketing materials.

The Satellite Town Ring Road (STRR) junction near Devanahalli provides connectivity to the airport road belt and will eventually link to Hoskote (east), Tumkur Road (west) and Electronic City (south). When STRR operationalises fully, Devanahalli transitions from a single-corridor location to a ring road node — materially improving its multi-directional commute profile. Read our Purva Northern Lights guide for context on the KIADB Aerospace Park employment anchor.

Birla Trimaya Floor Plans: All Configurations Explained

1 BHK (551–740 sq ft): Starting ₹70–75 Lakhs (Phase 2 pricing; Phase 4 starts approximately ₹82–90 Lakhs). Compact, well-designed format targeting young aerospace sector professionals, first-time buyers and investors seeking the most liquid rental asset in the Devanahalli corridor. At ₹70–90 Lakhs entry point, the 1 BHK is the most affordable branded new-launch apartment within 5 kilometres of the airport in Bangalore. Rental income potential at possession (2027–2028): ₹18,000–₹25,000/month. Gross yield: approximately 2.5–3.0% — above the Bangalore average for the asset type.

2 BHK (827–1,180 sq ft): Starting ₹1.10 Crores. The primary configuration by volume across all phases. At 827–1,180 square feet, Birla Trimaya's 2 BHK range covers both the compact (827 sq ft, approximately ₹1.10 Crores) and the spacious (1,180 sq ft, approximately ₹1.55 Crores) ends of the family apartment market. The compact 2 BHK is the best-value entry point for end-use buyers who need two bedrooms without the 3 BHK premium. Suited for dual-income professional families at the Aerospace Park or frequent airport users.

3 BHK (1,350–1,650 sq ft): Starting approximately ₹1.80–₹2.50 Crores depending on phase and floor. The family configuration targeting families with children or buyers who want a dedicated work-from-home room. At 1,350–1,650 sq ft, this is a well-sized 3 BHK for Devanahalli corridor pricing — comparable or larger than 3 BHK formats in Whitefield new launches at higher absolute prices.

4 BHK Duplex and Row Houses (2,200–3,050 sq ft): Starting approximately ₹3.50–₹5.18 Crores. Birla Trimaya's premium offering — duplex apartments and row houses in a gated township community. At 52 acres, the township has sufficient density to support a row house cluster while maintaining the 73%+ open space commitment. Targeted at senior executives, NRIs and buyers upgrading from conventional apartments to a more independent living format without leaving a gated community.

Birla Trimaya Pricing Analysis: What Phase You Buy Matters

Birla Trimaya's four-phase structure means entry price depends heavily on which phase you are buying. Phase 1 buyers in September 2023 got 1 BHKs at approximately ₹55–62 Lakhs. Phase 4 buyers in 2026 are paying approximately ₹82–90 Lakhs for the same configuration — a 32–45% increase over 2.5 years. This appreciation between phases is the compounded effect of construction progress (risk reduction), corridor maturation and general Devanahalli appreciation. Phase 4 is not the Phase 1 bargain, but it is not overpriced relative to the 2026 Devanahalli corridor benchmark of approximately ₹9,150/sq ft average.

At Phase 4 effective pricing of approximately ₹12,000–₹14,000/sq ft, Birla Trimaya is positioned above Purva Northern Lights at KIADB Aerospace Park (₹11,000/sq ft) and below Brigade Eternia at Yelahanka (₹14,000–₹15,000/sq ft). The Birla brand premium over non-branded Devanahalli launches is approximately 15–20% — justified by the township scale (amenity quality correlates with project size), the four-phase validation (three phases already selling with demonstrated demand) and Birla's corporate governance standards as an Aditya Birla Group company. All-in cost for a Phase 4 2 BHK at ₹1.10 Crores base: approximately ₹1.30–₹1.40 Crores including GST, stamp duty, registration and parking.

Birla Trimaya Amenities: What 52 Acres Delivers

A 52-acre township at 2,600 units means approximately 0.02 acres per unit — lower density than a typical Bangalore gated community project, allowing genuine open space. The 73%+ open space commitment across 52 acres means approximately 38 acres of the campus is green, recreational or open area. This is the largest open-space commitment by absolute area among all North Bangalore new launches reviewed in this series.

Confirmed amenity categories: club house with gymnasium, indoor sports and social facilities; temperature-controlled swimming pool; jogging track through landscaped open spaces; outdoor sports courts (tennis, basketball); children's play zones across multiple campus areas; amphitheatre; convenience retail within the township (Birla Trimaya includes retail space — a practical amenity that larger townships can justify); 24/7 security with CCTV and access control; EV charging; power backup. The mixed-use nature of the township — apartments, duplexes, row houses and retail within a single gate — creates a self-sufficient daily living environment that single-use apartment projects cannot match.

The upcoming Doddajala Metro Station (Blue Line, 2.5 km away) will provide direct transit from Birla Trimaya to Bellary Road, Hebbal, Manyata Tech Park junction, KR Puram and eventually Whitefield when operational. As with all Bangalore metro timelines, plan for a 12–24 month extension beyond stated targets. See our Bangalore investment guide for how metro activation has historically impacted corridor prices.

RERA Verification: Four Phases, All Registered

Birla Trimaya has four RERA-registered phases — an unusual structure that reflects both the scale of the project and Birla Estates' phased land development approach. Verify all four at rera.karnataka.gov.in:

Phase 1: PRM/KA/RERA/1250/303/PR/300823/006200 (1 September 2023) — 550 units, sold out. Phase 2: PRM/KA/RERA/1250/303/PR/040924/006988 (14 August 2024). Phase 3: PRM/KA/RERA/1250/303/PR/300125/007458 (18 January 2025). Phase 4: PRM/KA/RERA/1250/303/PR/290126/008436 (17 January 2026). When booking, confirm exactly which phase and RERA registration covers your specific tower and unit. Different phases have different possession dates — confirm yours in writing.

Birla Estates Track Record: What Has Been Delivered

Birla Estates was established in 2016 as the real estate vertical of the Aditya Birla Group — one of India's three largest conglomerates with revenues over ₹4.5 lakh crores and a presence in 36 countries. The Birla Group's corporate governance standards, financial strength and brand recognition provide a level of institutional backing that most standalone real estate developers cannot match. In Bangalore, Birla Estates has delivered Birla Alokya in Whitefield — a premium project that achieved strong post-delivery appreciation and is the primary reference point for evaluating Birla's Bangalore delivery capability. Birla Alokya's delivery performance, specification adherence and community management are the credentials that drove Phase 1's three-day sellout at Trimaya. Beyond Alokya, Birla Estates has active projects in Mumbai (Worli, Kalyan) and NCR, providing geographic diversification that single-market developers lack. For a 2,600-unit, four-phase, 52-acre township — the most complex residential undertaking Birla Estates has attempted — the Aditya Birla Group's balance sheet provides construction financing confidence that is rare in the Indian real estate market.

Birla Trimaya vs Competing Devanahalli Projects in 2026

Birla Trimaya vs Purva Northern Lights (KIADB Aerospace Park): Both are large-scale branded township launches targeting the North Bangalore aerospace corridor buyer. Purva Northern Lights at ₹11,000/sq ft is cheaper than Birla Trimaya Phase 4 at ₹12,000–₹14,000/sq ft. Purva Northern Lights has a larger clubhouse (100,000 sq ft vs Birla Trimaya's unspecified but proportionate facility) and is physically inside the KIADB Aerospace Park SEZ. Birla Trimaya is 2 km from the airport (better airport access) and has the four-phase demand validation track record. For aerospace professionals who work inside the KIADB SEZ, Purva Northern Lights is closer to work. For airport users and investors who want the Birla brand premium, Trimaya wins. Read our full Purva Northern Lights guide.

Birla Trimaya vs Brigade Eternia (Yelahanka): Brigade Eternia at Yelahanka is ₹14,000–₹15,000/sq ft — slightly more expensive than Birla Trimaya Phase 4. Brigade Eternia has superior established social infrastructure (metro 1.4 km, schools and hospitals today), better Manyata Tech Park proximity (15–20 minutes) and less airport proximity (19 minutes vs Trimaya's 2 km). Birla Trimaya is the better choice for airport users and aerospace professionals. Brigade Eternia is better for Manyata/Hebbal commuters and families needing schools immediately. Read our Brigade Eternia guide for direct comparison.

Birla Trimaya vs Godrej Ananda (Devanahalli, delivered): Godrej Ananda — the other landmark Devanahalli township, by Godrej Properties — is delivered and available on the secondary market at ₹9,500–₹11,500/sq ft. Ananda offers immediate possession (rent from Day 1), proven community living and established social infrastructure at the Devanahalli KIADB belt. Birla Trimaya Phase 4 at ₹12,000–₹14,000/sq ft is 4–47% more expensive than Ananda resale for the same corridor — the premium reflects the new-launch appreciation window and Birla's specification upgrade. For investors who want immediate yield, Ananda resale. For buyers who want new-launch appreciation and the Birla specification, Trimaya Phase 4.

Investment Analysis: Birla Trimaya Phase 4 in 2026

2 BHK scenario (all-in ₹1.32 Crores, possession October 2027): At 10–12% annual appreciation in the Devanahalli corridor over 1.5 years to Phase 4 possession, the same 2 BHK would be valued at ₹1.52–₹1.60 Crores — a 15–21% gain in 18 months. Phase 4 buyers are close to possession, which means the construction risk window is short and the capital locked is unlocked relatively quickly. Post-possession rental: ₹22,000–₹32,000/month for a 2 BHK near Devanahalli airport, a gross yield of 2.0–2.9% on total cost. Combined 18-month return: 17–24% total including first year rental.

Township appreciation trajectory: Birla Trimaya's multi-phase structure means that as later phases complete, the internal resale market within the township becomes more liquid. A Phase 4 buyer in 2026 exits into a township where Phase 1 and 2 residents are established — the community is functional, the amenities are proven and the resale comparables are visible. This township maturity effect typically supports premium resale pricing relative to isolated new launches.

Key risk: Devanahalli is dependent on the Aerospace Park employment cycle and the airport traffic growth. Both are structurally positive but concentrated. If aerospace sector investment slows or the airport's traffic growth underperforms, the demand pool for Devanahalli residential is thinner than a multi-sector IT corridor. NRI demand from aviation professionals who live internationally and want an investment near the airport provides a secondary demand layer that somewhat diversifies this risk.

How to Book Birla Trimaya Phase 4

Step 1 — RERA verification. Confirm Phase 4 RERA PRM/KA/RERA/1250/303/PR/290126/008436 at rera.karnataka.gov.in. Verify developer (Birla Estates), location and possession date.

Step 2 — Confirm your phase and tower. With four active phases, confirm in writing which phase, tower and unit number you are booking, what the specific RERA possession date is for that phase, and whether the configuration you want is available in the phase being offered.

Step 3 — Full cost sheet. Base price plus floor-rise premium, GST 5%, stamp duty 5%, registration 2%, parking ₹5–8 Lakhs, clubhouse charges and corpus. All-in for a 2 BHK at ₹1.10 Crores base: approximately ₹1.30–₹1.40 Crores.

Step 4 — Home loan approval. Birla Estates has tie-ups with HDFC, SBI and ICICI. All four RERA phases are eligible for home loan disbursement. For NRI buyers, read our POA guide. For all buyers, read our document verification guide before signing.

L K Monu Borkala's Expert Verdict on Birla Trimaya

Birla Trimaya is the most credentialed project in the Devanahalli corridor in 2026 — four RERA phases, Phase 1 sold out in three days, Aditya Birla Group financial backing and a proven township scale that no competing Devanahalli launch can match. For the right buyer, it is a straightforward decision. For buyers who do not fit the profile, no amount of Birla brand premium changes the fundamentals.

The right buyer: an aerospace professional, aviation industry worker, frequent flyer or NRI for whom proximity to KIAL is a genuine daily-life advantage; OR an investor with 3–5 year horizon and conviction that the Devanahalli airport corridor continues its current appreciation trajectory. For Manyata commuters, families needing established schools today or buyers who want metro access now, Brigade Eternia at Yelahanka or Godrej Woods at Thanisandra are better positioned. Contact OneCity Property for independent advisory before committing to any Devanahalli new launch.

Birla Trimaya Phase 4 prices (2026): 1 BHK from approximately ₹82–90 Lakhs, 2 BHK from ₹1.10 Crores, 3 BHK from approximately ₹1.80 Crores, 4 BHK duplex from approximately ₹3.50 Crores, row houses up to ₹5.18 Crores. All prices before GST at 5%, stamp duty at 5%, registration at 2% and other charges.

How far is Birla Trimaya from Bangalore Airport?

Birla Trimaya is located on Shettigere Road, 2 kilometres before Kempegowda International Airport on the main Bellary Road (NH-44) approach. This is the closest airport proximity of any residential township in Bangalore — effectively airport-adjacent for frequent flyers, aviation professionals and NRIs.

Is Phase 1 of Birla Trimaya sold out?

Yes. Birla Trimaya Phase 1 (550 apartments) sold out within three days of its September 2023 launch — one of the fastest sellouts in Devanahalli residential history. Phases 2, 3 and 4 are currently selling. Phase 4 received RERA approval in January 2026 and is the current active phase for new bookings.

What configurations does Birla Trimaya offer?

Birla Trimaya offers 1 BHK (551–740 sq ft), 2 BHK (827–1,180 sq ft), 3 BHK (1,350–1,650 sq ft), 4 BHK duplex (2,200–3,050 sq ft) and row houses. Total project: approximately 2,600 units across 6 towers of G+12 floors on 52 acres, with 73%+ open space.

What is the possession date for Birla Trimaya?

Phase 1 possession is targeted for October 2027. Later phases will have progressively later possession dates depending on construction progress and RERA registration timelines. Confirm the specific possession date for your phase and tower in the RERA registration and Agreement of Sale before booking.

Who is the developer of Birla Trimaya?

Birla Trimaya is developed by Birla Estates, the real estate arm of the Aditya Birla Group — one of India's largest diversified conglomerates. Birla Estates was founded in 2016 and has projects in Bangalore, Mumbai and NCR. In Bangalore, its completed projects include Birla Alokya in Whitefield.

How far is Birla Trimaya from Manyata Tech Park?

Birla Trimaya is approximately 25–30 kilometres from Manyata Tech Park via Bellary Road, typically 30–40 minutes off-peak. Devanahalli is primarily positioned as an Aerospace Park and airport-adjacent corridor — buyers who commute daily to Manyata should factor this distance into their decision.

What is the metro connectivity for Birla Trimaya?

The upcoming Doddajala Metro Station on the Namma Metro Blue Line (Phase 2B, KR Puram to Airport) is approximately 2.5 kilometres from Birla Trimaya. When operational (expected 2027–2028), it will provide direct metro access to KR Puram, Whitefield, and the airport. Confirm current timeline before treating as present-day connectivity.

Can NRIs buy in Birla Trimaya?

Yes. NRIs can purchase in Birla Trimaya under FEMA regulations for immovable property. An NRI needs a registered Special Power of Attorney (under the 2025 Karnataka Registration Amendment) if they cannot be physically present for registration. Read our Power of Attorney guide for the complete NRI process for Karnataka property purchases.

Birla Trimaya's Township Model: Why Scale Matters for Buyers

52 acres is a number that matters operationally, not just aesthetically. A gated community of this scale can justify amenities, maintenance infrastructure and security systems that smaller projects cannot — and can sustain them financially. Birla Trimaya's retail component within the township is a direct consequence of scale: 2,600 homes generate enough daily foot traffic to support a convenience retail strip, a café and service outlets within the gate. This self-sufficiency reduces the daily car trips residents need to make outside the community, which in a corridor where social infrastructure is still developing is a meaningful quality-of-life benefit. When the Doddajala Metro arrives, Birla Trimaya's township density also means the walk from any tower to the community gate and onward to the metro station is short — residents at the inner towers will essentially have near-walkable metro access, unlike smaller isolated projects at similar distances from the station.

The township model also provides resale depth that standalone projects cannot. When you eventually sell a Phase 4 unit at Birla Trimaya, you are selling into a market of 2,600 owners and their networks — plus the established reputation of a functioning township. The word-of-mouth resale network within a large township is consistently undervalued by investors who focus only on corridor-level appreciation and ignore the within-project liquidity premium.

Devanahalli 2026: Five Things That Have Changed Since Birla Trimaya Phase 1 Launched

The Devanahalli corridor Phase 4 buyers are entering in 2026 is meaningfully different from the corridor Phase 1 buyers entered in September 2023. Understanding what has changed gives Phase 4 buyers better context for their decision.

1. KIADB Aerospace Park operational headcount has grown. In 2023, Boeing India and Airbus were establishing facilities. In 2026, these are operational engineering hubs with hundreds of employees and active recruitment. The employment demand base for Devanahalli residential has deepened materially.

2. NH-44 upgrades have improved Hebbal connectivity. Signal-free improvements on the Bellary Road corridor between Hebbal and Devanahalli have reduced average commute times to the Manyata/Hebbal belt by approximately 10–15 minutes versus 2023 peak-hour conditions.

3. Blue Line Metro Phase 2B construction is visibly active. In 2023, the metro was a planning document. In 2026, construction of Phase 2B is physically underway and station sites are established. The probability of the metro delivering by 2027–2028 is now meaningfully higher than it was when Phase 1 buyers committed.

4. Average Devanahalli property prices have risen 35–40% since 2023. The ₹9,150/sq ft average recorded in mid-2026 compares to approximately ₹6,500–₹7,000/sq ft in early 2023. Phase 1 buyers who entered at ₹55–62 Lakhs for a 1 BHK are sitting on 35–45% gains before possession. This appreciation benchmark validates Phase 4's entry pricing as a continuation of a demonstrated trend, not a speculative premium.

5. Birla Trimaya itself is under active construction. Phase 1 is at an advanced construction stage. Buyers can physically see construction progress — the risk profile of Phase 4 is different from Phase 1 because the developer's capability, the township's viability and the community's formation are all visible and verifiable today in a way they were not in 2023. Read our RERA complaint guide for what to do if possession milestones are missed, and our OC guide for what to verify at possession. Contact OneCity Property for a site visit facilitation and independent advisory before booking.

Birla Trimaya Due Diligence: What to Verify Before Booking Phase 4

With four active phases and multiple configuration options, due diligence for Birla Trimaya requires slightly more attention than a single-phase project. These are the specific checks that matter.

Confirm which phase covers your unit. With Phases 1–4 simultaneously under various stages of development, the sales team may offer units across phases depending on availability. Confirm in writing: the specific RERA number for your unit, the possession date under that RERA, and the construction stage of your specific tower. Phase 1 is near possession (2027); Phase 4 is early-stage. The risk profile and wait time differ significantly between them.

Verify the RERA possession date vs marketing possession date. Sales teams sometimes quote optimistic possession dates. The RERA-registered possession date is the legally binding date — and is the date from which delay compensation under RERA Section 18 is calculated if delivery slips. Check the RERA portal directly for the possession date of your specific phase. Do not rely on the brochure date.

Check construction progress in person. Birla Trimaya is physically accessible at Shettigere Road, Devanahalli. Visit the site before booking. Phase 1 construction progress is visible and verifiable. For Phase 4, the site preparation and early construction stages should be visible. A developer who restricts site access before booking warrants caution — Birla Group projects are typically transparent about site visits.

Get the full cost sheet in writing. Base price, floor-rise premium, preferred location charges, GST (5% on under-construction, nil on fully completed), stamp duty (5% above ₹45 Lakhs), registration (2%), car parking, clubhouse charges, corpus deposit and advance maintenance. For a Phase 4 2 BHK at ₹1.10 Crores base, confirm whether you are being quoted pre-GST or post-GST and whether floor-rise applies to your specific floor. The difference between base price and all-in can be 20–25% on a Birla Trimaya unit.

Review the Agreement of Sale before signing. The AOS must specify your RERA number, possession date, delay compensation terms, carpet area (not super built-up), specification list and cancellation terms. Engage a Karnataka property lawyer for AOS review. Read our property document verification guide for the complete pre-purchase checklist. For NRI buyers, read our Power of Attorney guide for the 2025 registration requirements. Read our partition deed guide if buying jointly. Contact OneCity Property for independent pre-purchase advisory — we assist Birla Trimaya buyers at no cost.

Birla Trimaya at a Glance: Summary for the Serious Buyer

Birla Trimaya is a 52-acre, 2,600-unit, four-phase RERA-registered township by an Aditya Birla Group company, located 2 kilometres from Kempegowda International Airport. Phase 1 sold out in three days. Phases 2, 3 and 4 are all RERA-registered and selling. Phase 4 (January 2026) is the current entry phase. Prices in Phase 4 range from approximately ₹82 Lakhs for a 1 BHK to ₹5.18 Crores for a row house. The corridor has appreciated 35–40% since Phase 1 launched in 2023. The Blue Line Metro at Doddajala (2.5 km) is under active construction and expected by 2027–2028. Social infrastructure at Shettigere Road is developing but not yet as mature as Yelahanka or Hebbal.

If you are an aerospace professional, aviation industry worker, airport-adjacent NRI investor or a buyer with conviction in the Devanahalli corridor's 5-year trajectory, Birla Trimaya Phase 4 is one of the most credible entry points available in North Bangalore in 2026. The combination of Birla brand, township scale, four-phase demand validation and airport proximity creates a risk profile that is lower than most Devanahalli new launches at a comparable price point. If you commute daily to Manyata Tech Park, need established schools immediately or want metro access today, look at Brigade Eternia at Yelahanka or Godrej Woods at Thanisandra instead — both are reviewed in detail on this site.
