Style: Matter + WiFi + 8 AA batteries
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.

Eufy Smart Lock Review — A Huge Upgrade Over Schlage Encode After struggling with two Schlage Encode locks, I decided to replace them with Eufy smart locks, and I couldn’t be happier with the switch. My Experience With Schlage Encode Unfortunately, the Schlage Encode locks consistently gave me trouble. Despite repeated attempts, I was unable to update the firmware, and getting the locks to join my Wi-Fi network was frustratingly unreliable. A quick search online confirmed that I wasn’t alone — plenty of other users reported the same issues. These ongoing problems eroded my confidence in the Schlage devices. Why Eufy Stands Out In contrast, the Eufy smart locks have worked perfectly from day one. Setup was simple, and they connected to Wi-Fi without any hassle. The locks have been reliable ever since, with no dropped connections or update headaches. I also appreciate the build quality: The Eufy lock operates quietly — no loud clunking noises like I experienced with the Schlage. The rear latch feels solid, with no excessive play or looseness. Seamless integration with Doorbells like the e340 for unlocking Final Thoughts If you’re looking for a smart lock that simply works, I highly recommend giving Eufy a try. After my disappointing experience with Schlage, Eufy’s reliability and thoughtful design have been a refreshing change.

This lock seems to be great. Easy to install works great with matter. Has several options for locking and looks very nice. I highly recommend this deadbolt lock.

I have been using smart locks for years, and this is my third. The Eufy replaced an August lock, so that will be the direct comparison. The August just replaced the inside portion, so reused the deadbolt mechanism. This Eufy replaces the entire unit, which has both advantages and disadvantages. If you're a renter, or want/need to maintain the existing key, leaving the existing deadbolt is preferred. However, replacing the entire mechanism, like the Eufy does, allows for more features, like the included keypad and fingerprint reader. For the August, the keypad was an add on. The Eufy also included wifi built-in, where with the August it was a separate component that was plugged in near the lock. While that requires more batteries for the Eufy, I prefer the all-in-one solution. The other advantage of the Eufy replacing the entire mechanism is how much more positive and direct the lock feels when locking/unlocking it manually. The August would sometimes get out of sync, and when turning the lock knob by hand, it would engage the motor and you would be turning that, too. The motorized locking is also more precise, and quieter, on the Eufy. The last advantage is really only for those already using Eufy. Having it integrated with the camera app is great. If you have a camera at the entry, you can locl/unlock the door from the same screen as viewing the camera. The fingerprint scanner works great, and is faster and easier than using a code. The one complaint I have is in the app. If you add codes for people like pet sitters, cleaning people, etc., you are limited in terms of how you allow them to use the lock. It's either always or scheduled. And you can't change that without removing the code and adding it back. You also can turn a code on and off. You have to remove it and add it. That's annoying and an inexcusable oversight. Hopefully that will be addressed at some point, but I don't have high hopes.

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!

Easy to install and to get working with app. One of two kits was missing an insignificant part (rubber aesthetic plug) that customer support sent out to me quickly and free of charge. One of those upgrades that made me ask myself, "Why didn't I do this sooner?!".
