Auto lock when the door closes is unreliable. A third of the time doesn’t lock so have to be always on the lookout if door lock is triggered or not. Other than that it’s been good.

Bluetooth - checked, Apple home key - checked, Keypad - checked, Very clean look and functionality - checked, Price - checked. I was able to check all of my boxes with this lock. Simple, reliable (so far), no hiccups and relatively easy installation. The best part - you just bring your iPhone close to the keypad and it opens. No need to even turn your phone’s screen or go to the app - it works as a hotel key, just bring it close and it works. That’s what I was looking for when I did my research on the smart locks. The keypad is also great in case if you left your phone behind, no worries. It’s responsive and looks clean. I really like the overall design. It’s not bulky and feels right. What to watch out for: beware of a back lid where batteries live. It is HARD to remove. Every time I did, I thought I broke it. It’s tight and has nothing to do with how easy it looks on the instructions video. Believe me - it’s not the case. There is a little groove/slot to use the tool provided to open the back lid but when you do it literally feels like you are gonna snap it broken. Luckily it hasn’t happened yet, let’s hope it’s just the way it was designed and it’s gonna hold strong. But honestly - I’m not looking forward to the time I’m gonna have to replace the battery…

Works well with HomeKit via an AppleTV (acting as the Home hub). No issues with extreme rain, direct sunlight, and winter weather (the lock is fully exposed). Some issues noted in previous reviews are (sorry to say) user error. It's not super easy to set up: the lock needs to be set up using Bluetooth, which is fine because you do it once, or if you need to change a setting. There are lots of options to change in the app settings, but once you set it up in HomeKit, you can do the rest from Apple's Home app (or whatever home app you want). Where it gets confusing (maybe?) is setting up top automations. For example, we have two doors in a row, and the first lock and one tell the other to unlock to save tapping twice. I also had a light turn on automatically, but turning the light on/off triggered the door to unlock! The deadbolt hardware does seem "loose" compared to the old locks, but the deadbolt is super smooth to open and close (one finger), and we haven't had issues (even with kids slamming the door while the deadbolt is open).

Great lock unless matter support matters to you. This deadbolt never holds a connection to the aqara matter hub. Wish it had native matter support. Won't be buying aqara again.

This lock is so easy to install. It took me 30 min. and configure it with Apple Home was also vey easy and fast. Love the automations which I could program the lock tonopen or close at certain times and on certain days. Pretty good. No need to download the manufacturer app, it works just well. I can open lock with phone or watch. Manufacturer app sone extra features that I did not need.
