Good security but app could be better
The lock itself works flawlessly, and the auto-lock feature gives me peace of mind. However, the app sometimes lags or fails to connect, which can be frustrating. Still, for the price, it’s a solid smart lock option.

Great design and versatile unlocking methods
I appreciate the multiple ways to unlock the door – especially the keypad for guests. The lock looks sleek on my front door. It would be perfect if it supported more smart home platforms, but it works great with Alexa.
