Seller has poor packaging and no communication. No tracking info except it's delayed. Arrived late, severely damaged packaging.

These are great and keep us alert ‼️
These entry sensors help keep us safe by setting off an alarm when they are triggered. I appreciate that I will be able to know whenever a window or door has been opened by someone other than my family from across different parts of my house because I can hear the sensors beep when the doors are opened or closed as well as the windows 🪟. These are a great addition to our house security regiment and I feel knowing that I will be alerted if someone breaks in. Thank you SimpliSafe🙏

Door Sensors work great
The batteries work on all of the sensors. No problem linking them with the newer simplisafe base station. I used 3 of them on steel doors and the magnet part of the sensor pair just stuck to the door without any fasteners or adhesive. Been like that for a few weeks now and no movement.
