I like Aqara but it requires hubs to maximize the features
The Aqara U300 works great! I really love the passcode, fingerprint, and Bluetooth access. My house is about 2,200 sq ft, and I’m able to control the lock via Bluetooth throughout the entire house without any issues. If you want NFC or Apple Wallet features, you do need to purchase an Aqara Hub, but overall the user interface and functionality are excellent. Installation was easy for me since my garage door already had a handle-style lock. It is definitely more expensive compared to other smart lock systems, but in my experience, it’s worth it. I previously used an August lock, and the connection was very inconsistent. The Aqara U300 feels much more reliable and polished in comparison.

Loose exterior handle (received ANOTHER BAD lock from Aqara Customer Support)
UPDATE 2: Received and installed the replacement lock a few months back, and now the handle of the new lock is also becoming loose (it is about as loose as was the previous handle, just before it fell off.) There is nothing special about this door, or how the handle is used. I asked Aqara Support to review the issue with the engineering team. If the issue has been fixed, perhaps by simply using thread sealant on those tiny screws, I would be happy to try another handle but for now I unfortunately have to rate this product with one star. Aside from this issye it's a good lock, but this is a complete deal breaker. UPDATE 1: Aqara Customer Support did eventually respond to my concern with the loose exterior door handle. I imagine the issue described below still exists so bumped the review to four stars, hoping Aqara will after this issue and more securely attach the handle in a product update. ORIGINAL REVIEW: The exterior handle came loose about two months after installing and moderate use. Contacted Aqara support multiple times and received nothing but questions and irrelevant video links clearly meant to deter me from pursuing having the door handle repaired or replaced. After asking for a resolution, Aqara Support stopped responding altogether. I am very disappointed with the quality and lack of support. DO NOT BUY FROM THIS COMPANY. There are plenty of other great product from reputable businesses! The door handles look ok and I like the idea of Matter + Thread support, but it is not worth investing in a product that breaks and where no support if provided by the company.

Just great. Really happy.
We got a bunch of U100 and U200 locks previously and Aqara lying to us! The batteries last a lot longer than they say! And I pass through our doors a lot more often than the average person. And yes, I'm in a cold climate in both Detroit where we lived and now in the mountains of West Virginia. For the house in WV I ordered six of these and installed one to date. Did so right at the beginning on the cold. When I installed the lock it was 70º, sunny and beautiful. By the time we left it was 24º and the lock was crusted over in a thick layer of ice. Get this! The lock read my thumb print through the nice - no problem! And the keypad also worked brilliantly. I've got to say Aqara, at least with their lock products, seems to have an "under promise and over deliver" policy and I love it! I don't like to mention competing products in reviews but I've got to say: I removed our top-of-the-line Level Lock Plus in favor of an Aqara lock. They're more responsive, less troublesome, and far more trustworthy as devices go. You get the sense from their marketing that Level is the top of the heap but they're not. If you're running an Apple Home these are the ones you want. Turn on Express Passage and your door unlocks the first time you raise your device to it - every time, though you'll never use the feature with these as the thumb print is so much more convenient. I don't work for them. I didn't receive a test product. I'm just a really, really impressed and extremely happy customer. Aqara did it again with the U300. It's about as perfect as lock as you could hope for if you're needing a smart knob-replacement lock that truly supports your chosen ecosystem. Go on and buy with confidence. These things are dope. ❤️💋 Regarding some of the issues reported by users here and in other places: 1) Communication issues are likely environmental in my experience. Make sure you have an AppleTV, HomePod, or HomePod mini within 30ft of your lock. Make sure there's no brick and very little plaster and lathe between your lock and your HomeKit or Aqara hub. 2) Apple Home, HomeKey and other issues: Just remember you don't actually need the Aqara App if you're using HomeKit. It's a good idea to use the app so the lock is associated with you through their app and your account, but the app itself has nothing at all to do with HomeKit. In fact, anything you do through HomeKit is written to the lock separately. They're two different worlds and Aqara was wise to keep them separate. 3) If you're thinking about a smart lock have a look at your door first. If your closure is weird or unreliable, if after your close your door you notice there's a lot of pressure on the knob latch, or if your door frame has simply relinquished "square", this or any other smart lock is likely going to be problematic. Manual locks on doors that require fidgeting to make work are generally fine because they're manual. But those same doors are likely to introduce problems as most smart locks are made for new doors, or at least doors that close and rest properly. Be sure to assess your door first, If it has problems get those addressed BEFORE trying to install any smart lock. A bad closure will see your locks fail, not last, batteries may die faster...

Work Well Feels Solid/Premium.. Pairing to the Aqara M3 Hub Thread over Matter was a little Gimmicky.

I bought this lock for my bedroom, and it's easy to install as long as your door has the standard holes. Till now it works well. You'll need a Matter hub to monitor.

1 star because I can’t give less. First one I purchased moisture developed under the keypad after a few months. Contacted them, they sent a replacement. The replacement came and would not setup. The main pad stayed dark so it could not be used. I was asked to send a video, which I did. Their email could not accept the video, so I had to compress them send and after a week I got a response saying they needed a longer video of me going through the setup process, which I couldn’t because there wasn’t a working pad. Needless to say I did not get a second replacement. Also the iPhone setup is horrible. After hours of googling and YouTube videos I finally managed to set my phone up to unlock (which is the only reason I purchased this model to begin with) Please do not purchase this product, it will only last a few months and give out. Absolute garbage.

Great features especially for those in the HomeKit / Apple ecosystem. The security options from old school key, Apple Home Key, fingerprint, or even nfc card is super convienent. The handle form factor works great on my garage door entry way to the house.
