SimpliSafe Entry Sensor (Pack of 4) - Window and Door Protection - Compatible with The SimpliSafe Home Security System - Latest Gen

Cheaper than ordering from Simply. Working great.

Matches the ones I have

Need a few more for our system,work great

Very easy system to install. I purchased these to complete installation and secure our home. Im very pleased with how easy it is to set it up and connect. Plus, appears to be a U.S. based call center with outstanding customer service. Wholeheartedly recommend SimpliSafe to anyone considering an alarm system.

Great system and works very well.

Purchased as a backup for previously installed ones , hope to not need . The ones in my system are great .

Great Window and Entry Sensor. Great Price. Easy to install and program

I did not install these until weeks later and then realized that these are worthless unless you buy into the whole system. Return window had passed. Lost $60

All simplisafe parts work I have used Simplisafe for years and have never had to replace any parts.

I had one sensor with the system that went off and on. The replacement has held up, so far. Great system!
