### ⭐⭐⭐⭐⭐ Very Small and Hidden Door Sensor
*by R***3 on September 14, 2023*

I was looking for a basic wired door sensor to install in my doors for Home Assistant and these were perfect, the sensor is so small it is hard to see it once installed, exactly the look I was going for.

### ⭐⭐⭐⭐⭐ Good product
*by H***P on February 14, 2020*

Was exactly as described and worked perfectly!

### ⭐ Unreliable - DO NOT BUY!
*by B***T on April 18, 2023*

These magnetic alarm sensor switches are low quality and totally unreliable. The switches (all 5 in a pack of 5) stick in the closed position once activated. Do not waste your time and money on these.
