Reviews often mention that the lock starts to get noisy over time, making a rattling/grinding sound and sometimes failing to unlock. I experienced this same fault after about a year of use. If your motor is still running but the lock has trouble turning, the problem is in the gearbox. I disassembled the lock right down to the gearbox (it's not difficult, there are plenty of video tutorials on YouTube). I cleaned out the old lubricant and applied new grease. Since then, the lock has been working for another year without any issues and I'd say it even runs better and more smoothly than when it was new from the factory. Inside the gearbox is a combination of metal and plastic gears, which were mechanically fine and just needed some maintenance. IMPORTANT REPAIR NOTE: Be careful with the amount of grease – don't use too much! On my first attempt, I overdid it and the lock didn't work correctly. I had to take it apart again and remove some of the grease, and only then did it work as it should. If you're a bit handy and have this problem, definitely give it a go, it's worth it.

It worked well, but only for two years and two months. Something inside the gearing broke right after the warranty expired, and now it just buzzes and growls but won't open.
apart from the fact that it only lasted for the warranty period, probably nothing

I have complained about the lock twice already and each time the same problem - broken connection and wrong calibration. The product behaves unpredictably, which is a major problem with the lock. Alza did not resolve the situation and only blamed it on the need to update the software. The update didn't solve anything, of course. Overall disappointing. For the money, absolutely unacceptable quality. I would definitely not buy this lock again.
Modern design
Theoretically interesting features (apps, smart controls)
Extremely unreliable connection to the app
Common lock calibration problems
Unstable functioning (sometimes not responding at all)
Low quality of workmanship relative to the price
Complaints without a real solution

Worked well for almost a year
We used only local, no Matter connection
after a year, it rattles, sometimes it doesn't unlock, so you can't rely on it.
I'm filing a complaint, even though I don't expect it to be resolved
quite noisy

The initial enthusiasm was replaced by disappointment with the quality of the product.
It worked for the first year
After a year, the lock started to jam
Bluetooth fails, works after removing and removing the battery.
When Bluetooth fails, it loses communication with the keyboard
After the complaint, the problem was not solved

Initially, the lock worked well, and I have to commend both the integration with HomeKit and the many ways to control the lock. Whether it's a keyboard, a fingerprint, or even the Apple Home Key on your watch or phone. Unfortunately, after about 7 months the lock started to jam and now it works only sporadically, or it doesn't work. Calibration will only help for a few cycles. According to reviews from previous users and general feedback on the internet, users have the same problem with this lock everywhere. Even after the complaints have been settled. So I can really hardly recommend this product.
A good lock when it works.
Unfortunately, it soon stopped working. i.e. complaint required!
