Spec, translated

The 'Perovskite Solar Power' feature uses a novel solar material to trickle-charge a very large internal battery. This drastically reduces how often you'll need to manually charge it, but it does not make the lock fully self-sustaining in all conditions.

Lab notes
The observations that actually change the buying decision.
01
The BHMA Grade 3 certification is the lowest residential standard for deadbolts. This lock provides basic physical security, not high-end protection against forced entry.
02
An IP53 rating protects against light water spray, not driving rain or jets of water. This lock is only suitable for doors with significant overhead cover, not those fully exposed to weather.
03
The 37Wh battery is exceptionally large for a smart lock. The perovskite solar panel is a trickle-charger designed to extend its life, not eliminate the need for eventual USB-C charging.
04
Palm vein recognition is, in theory, more secure than fingerprint scanning as it reads subdermal patterns. Its real-world speed and reliability in direct sunlight or extreme cold are unproven.

Why you should buy

This lock is for tech-savvy users on a budget with a well-covered entryway. If you value native Matter integration, novel biometrics, and extremely long battery life over maximum physical security, the feature set is compelling for the price.

Why you should skip

Anyone requiring high physical security should seek a BHMA Grade 1 or 2 lock. If your door is exposed to wind and rain, the IP53 rating is a non-starter. Buyers prioritizing proven long-term hardware reliability over bleeding-edge features should wait.
