    Absolutely love it. It connects to the HomeBase 3 and then Matter. It responds quickly to touch and is smooth. I purchased a Schlage Bowery knob with Collins trim in matte black and it’s the perfect setup. I had the local Ace rekey the knob for 10 bucks and I am all set. Perfect match.

    Strong, sturdy and smart high quality made! I had bought some no branded all in one security locks off Amazon seems cheap with plastic parts inside. Even the smart settings become dumb settings. My first Eufy product is greater than any other brand i tried

    Eufy Smart Lock Review – Seamless Upgrad

    ust installed my first smart lock and couldn’t be happier with the upgrade. The installation was straightforward—clear, accurate instructions made the whole process smooth and stress-free. Visually, it’s a sleek addition to the door, with a modern look that fits right in. Programming access codes and fingerprints was surprisingly simple, and integration with my Alexa smart home setup was seamless. Now I can lock and unlock with voice commands or remotely—huge convenience boost. Overall, it’s a solid piece of tech that delivers on both form and function. Highly recommend for anyone looking to level up their home security without the headache.

    I bought this product after getting locked out of the house! This product gives you the option to use your finger print or a digital code to open the door! It’s also very easy to link to your phone and you recieve text alerts whenever the door is unlocked. You can also lock and unlock the door through the app! Very easy to install.

    I recently switched from Yale. Used it for 2 years and 2 months. Something kept draining my batteires with Yale every single week. They offered no help and the Matter upgarded was an additional $200! This Eufy has everything you can think of and even a rechargeable USB-C battery! Love it! I will get all Eufy locks for all my external doors!

    This does the job well and I like the fact the battery is rechargebale. My experience with this brand is I dont have to recharge this for at least 6 months even on a busy door. I like the fact the kids dont have to walk with keys and it is very durable.

    Im tied into the Apple Home ecosystem. This was one a few that I found attractive and supports Apple Home. Other than a few comnection issues that required removing the device and re-adding it, this has been solid. The finger print reader is quick and the app seems stable.

    Super convenient and very secure! I love that I can unlock the door from the app or use my fingerprint — no more searching for keys. The setup was quick, and the connection to Wi-Fi is stable. It looks sleek on the door and matches my other smart devices perfectly. I’m really happy with this purchase and would buy it again.
