Feels like a lock Apple would build
I've owned several smart locks over the years. The Aqara U300 is my favorite of them all. PROS - 1) Simple installation - if you use HomeKit it integrates into Apple Home easily without need for a separate WiFi hub, the Aqara locks were built for HomeKit so this feels like the closest thing to an Apple built smart lock. 2) Sleek design - no bulging battery pack on the inside, small footprint for the equipment on the outside, hands down this is the best looking smart lock I've ever seen. 3) Fingerprint scanner is very quick - sets up a lot like a fingerprint ID on an iPhone 4) Apple HomeKey is incredible - HomeKey is added to Wallet on iPhone (of all Household members of your Apple Family who have access to Home) automatically when the lock is added to Home. Just tap your iPhone or Apple Watch on the outside display and the lock opens immediately, you don't even need to turn on your iPhone or Watch, just tap and open the door. CONS - 1) No WiFi connection to Aqara APP - only connects via Bluetooth. Which isn't too much of a hassle, because once setup through Apple Home, remote operation (locking and unlocking) is available. But you need the Aqara app to setup additional users, their passcode and their fingerprint scan, all things that need to be done close to the lock, so lack of a WiFi connection on the app is not a deal breaker. But just be aware, if you are adding additional users, you need the Aqara APP, and you need to be very close to the lock. 2) It RE-LOCKS very quickly. When you unlock this lock you have a very short time to open the door, or it will re-lock. I understand wanting to keep the house secure - but there are times when a 10 minute delay re-lock would be helpful - like bringing in your groceries from the garage, your hands are full it's not convenient to be trying to put your thumb on the fingerprint reader, or trying to tap your Apple Watch on the display. There is a setting in the Aqara APP called PASSAGE MODE - I set that to 10 minutes. To activate PASSAGE MODE, you need to push a button on the top of the inside portion of the lock, and verify with a passcode, fingerprint or Apple Watch / iPhone bump on the outside portion of the lock. That then stops the lock from re-locking for the set amount of time - IF you remember to hit that little button. It would just be easier to have the 10 minute delay activate every time. Lots of PROS for this lock - and a few CONS - but a HIGHLY recommended smart lock!!

Defective lock
The lock worked fine for about 45 days, but then I got an error message saying the latch malfunctioned. I could not open the door from the outside. Luckily, it was in my garage, so I was still able to get in. I escalated to Aqare support, which was an absolutely horrendous experience. The rep first asked me to send an image of the error message. I did. They then asked me to check a few items and to send them videos of the lock malfunctioning so I did. I included videos of the latch not working when attempting fingerprint entry and even using the key. The rep only told me that I installed it wrong. The next day the lock wouldn't open from the inside either. The latch was clearly defective as it started falling apart. I asked the rep to send me a replacement device and they just ignored my message for over a week. I ended up setting up a replacement via Amazon. Ok product if it was just a defective device but it seems this is a common issue. Support is terrible. I would not recommend this to anyone.
