Great smart lock
So far good. I would say the lever can be less flimsy but it works always. The battery notification is helpful and the auto lock function works well too. Installation is fairly easy, just follow the instructions. However i have to say it is difficult ish to get the seal to properly seal the lock against the door for weatherproofing it. For the price, this is an excellent smart home lock that you can open/close from anywhere. No additional subscription needed. I actually used this to replace my schlage. The schlage build quality is nicer but i don’t think it’s 8x nicer compared to this.

DO NOT BUY!!!
I have been an Anker/Eufy fan for many years and have owned several of their products, but this has been my worst experience yet. I bought two of these locks, and while both installed easily and worked fine for about two weeks, they eventually went offline. I tried restarting my WiFi and removing and reinstalling the batteries, but neither lock would reconnect to WiFi. At this point, both locks were still connecting via Bluetooth. I then visited Anker’s support site, which directed me to completely reset the locks. Following their instructions, I reset one of the locks, which caused it to be completely removed from the Eufy app. When I attempted to set the lock back up in the app, it consistently failed at the WiFi setup step and could not be added back to the app. Since it is no longer set up, this lock cannot even be controlled via Bluetooth. Frustrated, I contacted support (which is only available via email). Over two weeks, I went back and forth explaining and re-explaining the issue. In the end, support said there was nothing they could do and advised me to use Bluetooth to control the locks. Because of the time wasted working with support, I am now outside the return window. As a result, I have one lock that is completely disconnected and cannot be controlled at all, and another that can only be controlled via Bluetooth when standing right next to it. Terrible experience!

The Matter is amazing!
The Eufy Smart Lock is a sleek addition to any home security system. It offers keypad entry and mobile app control. As an owner of various Eufy devices, I value how well they integrate into their ecosystem, allowing for easy monitoring and access management. The keypad works well in various weather conditions. With impressive battery life and backup options, the Eufy Smart Lock is a reliable and convenient investment for enhanced security.
