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

As expected

I ordered and didnt notice that the system is not backward compatible with orginial system

Seems like a good product for the money, as well as easy to install and set up with what I already had.

A great system

Love all simplisafe products. Work really well. Absolutely recommend

After just moving and having to add 23 more entry sensors, one can see how purchasing these directly from Simplisafe could be quite expensive. This package makes it easier and more cost-effective to add more sensors to your system while saving some money in the process. Definitely worth the purchase.

After moving to a new home I needed to add more sensors to my house. So I bought two packs of four of these. Upon installation three out of the eight register as having low batteries. I don’t really understand how because you have to pull the battery savor tabs out before you install them. I contacted Amazon and their resolution was to send me batteries to fix the problem. Although I’m happy that they’re making it right it’s frustrating that a brand new product had batteries that were already not good. All of the others work perfect we’re easy to install and my system is up and running perfect. So five stars for the product when it’s working. They are very easy to install and a good value for your money. One star because three out of the eight had bad batteries.

We love our Simplisafe system. Great monitoring price and very happy with the quality of the products they sell.

Had one sensor go out, purchased this as a replacement. Simple to install. Works perfect.

Love simply safe. Best home security system we have ever had!
