### ⭐ Very bad
*by A***I on 8 November 2024*

Didn’t last a month and since the start the unit is defective. Intermittently the status remains open though the door is closed I have very minimal gap between the sensor units .

### ⭐⭐⭐ Does the job but battery doesn't last long...
*by R***N on 24 March 2023*

Enough to notify you if a door or window opens or shuts, but the battery barely lasted 2 weeks and I did not get a battery notification, seems that is can't detect the AAA battery capacity nor discharge rate...
