## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by M***Y on June 24, 2025*

This product works really well. I put it on my door and every time the doors open I get notification that the door was open in time. Good alarm system . All you need to do is download app… this is so good. I’m thinking to buy another one for my window.

### ⭐⭐⭐⭐⭐ Good Functionality!
*by I***Z on April 11, 2025*

Very good functionality. I will buy more to others doors.

### ⭐ Slow and inaccurate detection
*by R***Y on May 16, 2024*

I have some similar sensors in ZigBee format and they operate as expected. Thought to try the WiFi version at another property. Well these sensors do detect state changes it is very slow, controlled and intentional. When opening and closing doors normally it may detect 15-20% of the movements. The reporting is really slow to smartlife, also once a state changes it takes a long time to report changes. I would not recommend, not too sure f its due to WiFi or what, but ZigBee ones seem fine and show at least 95% accuracy and reasonable reporting times not these.
