The Eufy ecosystem is very good, I’ve had it for five years now. Just needed more entry sensors which was easy to synchronize or connect to the WiFi and the system and it works well. The adhesive is good, it sticks properly to the surface of my window really good. I would recommend the entire Eufy ecosystem if you want a reliable security system for your home. Remember you can set up the entire system yourself. It’s that easy.

An all-round great product, set up was easy, and they are super reliable. I just took them out of the box, loaded the included batteries into them, and placed them on my door and door trim, and it worked like a charm. The adhesive strip on the back of them allows you to readjust the sensor and magnet a few times without losing any strength, so you can find the best spot to place them, making sure the gap between them is less than 4cm. When testing, I armed the security system and opened the door as if I were an intruder, and the alarms started blaring instantly. I also got a notification on my phone as soon as it happened. No regrets adding this to my security system

This is the second unit that I have bought. The first was about 4 years ago probably when eufy first brought it out. I was pleased with it then and am still. The device has proven to be completely reliable. I decided to alarm the my outside garage door which is used by service personnel on a regular basis. Mounting the two pieces was easy using the applied sticky pads. The sensor/transmitter per the instructions can be attached with screws. The two pieces can be installed on any standard and patio doors. The audio alert can be heard throughout my house as the volume and signal can be set in the app. The eufy home base and app allows me to receive notices on my phone when away. The sensor/transmitter uses a not so common battery that is said to last 8 months. I've changed the battery in my original unit once in 4 years. I've installed another manufacturer's door and window sensors in another house. The unit is much smaller and uses 2032 batteries that in my experience don't seem to last as long as the eufy battery. On a door the eufy size is not a problem. I can recommend it as I just bought my third unit.
