## Description

eufy FamiLock S3 Max

Review: ease of installation and the application is easy to use - very easy to setup and it has so far been a great experience using after changing from another devise model
Review: Anyone in the house can immediately see who’s at the door without your phone! - I hated that nobody could see who was at the door unless they had my phone. Now anybody who is home can see who’s at the door immediately, plus I still get the notification on my phone so I can continue to monitor while I’m gone or if I just don’t feel like getting my ass off the couch! I can see who it is, unlock it, and remind them to be quiet coming in because the baby’s sleeping, all without even having to get out of my comfy spot! The kids think the hand scanner is the coolest ever, and I love that the notifications come to my phone with their name, what they did, and what time. “Johnny unlocked the frond door with his palm at 10:03 PM” - BUSTED Johnny! You were late! You can also assign different people different codes so you always know specifically who’s unlocking it (plus you have them on video). You can create temporary access or set up a schedule for access or turn their access off at anytime! It’s really easy to install and set up. I love that eufy doesn’t make you pay for a monthly subscription to use their products. I like it so much I’m currently working on changing out all my blink and myQ security devices for eufy. Little more pricy but worth it to have all reliable devices on one app that work together. You can easily lock or unlock everything all at once! App is very simple to use! If you’re looking for something to keep a reliable eye on your place, and something other people in the house can without your phone, this is worth it!
