After 3 months of using the VLUOO Electronic Deadbolt, I'm impressed by its sturdy zinc alloy build and multiple unlocking options. The remote control's 10m range is perfect for my garage - I can unlock it while carrying groceries without fumbling for keys.

The TTLock app integration is a game-changer. I once let a neighbor in while on vacation by remotely unlocking via Bluetooth. However, like some reviewers mentioned, the remote's battery life disappointed me too - mine lasted only 2 months before needing replacement despite the promised 5-year lifespan.

Installation was straightforward (took me 20 minutes), though the manual could be clearer about app setup. The dual deadbolts feel incredibly secure - much thicker than my old traditional lock. During a recent cold snap (-10°C), I noticed slight sluggishness in operation, but no complete failures.

What surprised me most was the emergency manual override feature. When my phone died unexpectedly, I could still operate it mechanically - a crucial safety backup many smart locks lack.

While not perfect (I wish it worked with standard batteries), this lock provides excellent security at its price point. Just keep spare batteries handy for the remote!
