Easy Setup, Great Price, Works Seamlessly!
I’m really impressed with this product. From the start, installation was super simple—I had it up and running in just a few minutes without needing any extra tools or complicated steps.The cost is very reasonable compared to other options I looked at, and honestly, I wasn’t expecting it to perform this well for the price. It feels like a great value.Day-to-day use has been smooth and straightforward. Everything works exactly as it should, no hassle. I also love how well it integrates with my smart home setup—it connected right away and responds quickly to commands.Overall, I’m really happy with it. Easy to install, affordable, simple to use, and smart home–friendly. Highly recommend!

Don't to get ir fast
I recently installed this smart lock on my front door and it has been a game changer! Setup was quick and easy, and the app is very user-friendly. I love being able to lock and unlock the door from my phone and give temporary codes to family or guests—it makes things so convenient.The build quality feels solid and secure, and the fingerprint/keyboard access works flawlessly. Battery life is great so far, and I like that it gives notifications if the door is left unlocked. It’s modern, reliable, and adds an extra layer of security and peace of mind to my home.Highly recommend to anyone looking for a dependable smart lock!

Easy set up for the girlies.
I had a pretty bad allergic reaction that made me stay in the hospital for a few hours and no one had the keys to my apartment to keep an eye on my dogs. Decided to get this just in case I had another incident of the sort. Ordered it from Amazon and it never arrived but I ended up getting it in person and it has been the best purchase I've ever made. The set up was easy, the lock functions well and it looks fancy. Only downside that it has is that it doesn't have battery included. However, I bought the rechargeable batteries and the battery last for almost 3 weeks. Im 27, live by myself, and I was able to install it without help.

Great minus battery life
I love this product and all eufy products. I bought this about 6 months ago, along with the eufy camera. Didn’t want a subscription so though this was a great alternative! Super easy to setup, step by step guide and videos. And linked with Amazon Alexa in a snap.The only thing isn’t I have to change the batteries maybe 1 a month and I feel like I barely use it besides manually locking it. Along with the fact I have no idea when batteries are dead or nearing the end. And than once I have new batteries, I have to re connect to WiFi and setup.l which sometimes relays the connection.I wanted a key pad incase needed people to have access to my house while I am not there, but since I can’t relay on it having battery life I have to just hand out keys.

Good customer service
ProsFunctionality wise, it works well, app is easy. Notifications are quick and reliable.ConsI had some issues, well outside of the return period. Customer service was very proactive and took care of me 100%. I believe I just got a defect, which can happen to anyone - how the company handles it is what is important. Would buy another Eufy product without hesitation

Excellent entry level smart lock
Deadbolt lock only. No handleThis is an exceptionally good purchase for a Eufy deadbolt smartlock. I have installed several of the higher tier Eufy smart locks with fingerprint detection and the steps for installing this lock are identical.I installed the lock on my backyard storage shed after losing the keys for the “traditional” deadbolt lock and wanted a solution that doesn’t tie me to having a physical key.The configuration is simple using the free Eufy app and managing users and notification is a cinch.

Great setup, durable and easy to use
Great setup, durable and easy to use.Great lock that needs no “hub”. Connects to your home WiFi. May control or receive log remotely.This is a no brainer. The user interface and programming features allow for easy expansions (more users / access , more items)

Very easy install, Battery life could be longer
Installation was very easy. Instructions are pretty simple and the video is easy to follow. I have had no issues with connectivity even for my lock in the garage. The app is really simple to use as well.I bought two of these locks. So far I’ve only had to replace the batteries once in a 2 month period in my most frequently used door. The less frequently used door I’ve had to replace the batteries once after about 3 months. Definitely recommend purchasing rechargeable batteries. They have stopped me from worrying about having batteries and the cost of them.
