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...

Confusing installation process in the app when setting up Apple HomeKey
The installation was a bit tricky because of the way my garage door is configured from prior owners. Aqara didn't include the installation manual so you have to use their QR code to get/view the manual online or watch their installation guide video on YouTube or here on Amazon product page. After tinkering around a bit to have it match to my current door configuration, I was able to install the device (I had a hard time fitting the inside portion of the door handle to match the lock plate -- just make sure you align the shaft and the locking plate perfectly so that the shaft is perfectly aligned in the middle of the locking plate hole). So I open the Aqara app (I already have the U100 so I thought it was a similar process to set up Apple HomeKey), but it seems to have an issue with Bluetooth -- it will constantly say "Offline" in the app once installed. The only way it wakes up the lock is to actually tap into the device in the app to connect to Bluetooth. After trying to figure out how to set up Apple HomeKey in the Aqara app, it was nowhere to be found, and it kept telling me to install it through Matter which requires their proprietary hub (which I don't have because I use Apple HomeKit). So I was confused and decided to open the Home app in my iPhone, clicked on add accessory, and it was able to detect the U300 so I added it that way. It will ask you for the QR code or the device number which is going to be located on the side of the door handle where it says "Matter." I hoped the Apple HomeKit/HomeKey installation process would be smooth, but it wasn't, and was quite disappointed. In terms of door functionality, it seems to work as I had hoped for so I'll give one star. But, it's losing 4 stars because of all the hiccups and the lack of guidance when installing the device (alignment issue should be mentioned in the installation manual), device constantly saying "offline" due to Bluetooth issue, app not implementing Apple HomeKit/Key, and having to install it through the Home app by myself after I figured it out by myself without Aqara's assistance.
