Very cool

[This review was collected as part of a promotion.] The palm unlock feature is seriously cool — feels like something out of the future. Just walk up, hold out your hand, and the door unlocks like magic. One thing I really like is the camera notifications. I get alerts right away when it senses someone at the door, even before they ring the bell. It’s peace of mind, especially if I’m not home or expecting a delivery. Setup was really straightforward — hardware install took maybe 15–20 minutes, and pairing it in the app was smooth. If you’re looking for a smart lock that combines cool tech with real-world convenience, this one nails it. Definitely feels like the most complete package out there right now.

Good

[This review was collected as part of a promotion.] This electronic lock was pretty good. We used it on our back porch door and it was helpful when my daughter wanted to go in and out to the backyard. Thanks!

High Quality

[This review was collected as part of a promotion.] A really cool piece of tech. My husband found it easy to install. I love the high resolution on the video camera, it has so many features like the palm recognition that we are just starting to use. Definitely a bug upgrade from our previous one.

Smart, secure, and effortlessly convenient

[This review was collected as part of a promotion.] I absolutely love the Eufy Security S3 Smart Lock — it’s one of the best smart home upgrades I’ve tried. Installation was quick and straightforward, even though it didn’t come with printed instructions. Thankfully, the Eufy Security app and online resources made setup simple, and I had everything running smoothly in no time. One of the standout features for me is how powerful and user-friendly the app is. I can lock and unlock the door remotely right from my phone, which is incredibly convenient when I need to let someone in while I’m not home. The app also makes it easy to add and manage other users, so family and friends can have secure access without needing a physical key. Another huge bonus is the built-in video and motion detection. I can see a live view of my front door anytime, and the app records any motion it detects. The two-way audio is fantastic, I can talk to anyone standing at the door and hear their response, whether it’s a delivery person, a visitor, or just to give quick instructions without opening the door. The palm-reading technology is a cool, futuristic touch. While it’s not 100% perfect every single time, it works well and makes unlocking the door quick and hassle-free without keys or even my phone.

One of the coolest locks on the block!

[This review was collected as part of a promotion.] I love how this has palm vein recognition and a high-resolution camera that offers advanced features not commonly found in standard smart locks. It can be a bit big but some may really like that.
