I've tried many smart locks, but the one I keep on my door is still $133 after Prime Day
Briefly

Getting the Aqara U100 on my front door was reasonably straightforward, even though my specific review unit didn't come with instructions. It took a few minutes to figure out which piece goes on before the other, but a deadbolt is a pretty straightforward mechanism, so it was easy. The entire process took less than 15 minutes.
the U100 lock features a keypad to enter 6-10 digit passcodes to open, and users can add one-time passcodes or ones that only work during a preset period, like for a babysitter every weekday from 3-6 p.m.
After setting up my U100 to open with my fingerprint, I've never had issues with it not recognizing my print or failing to respond to it. Users can add up to 50 fingerprints in the app, and Aqara says its fingerprint reader features a 98.6% recognition rate.
