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

Alarm went off and could not figure out why. Finally found the sensor had detached from the door and fallen behind a box. Picture shown in sensor the next time it fell off. Product is useless if the tape is no good. This help for 40 days before failing. I do not recommend this product if you plan to use it on high gloss surface. I am going to have to permanently attach it to my door.

I needed a few more than I had originally thought. So this four pack solved that problem. East to install and set up. And all work perfectly just like the first ones I purchased. And they arrived quickly so I only had a couple days to wait before I could protect those last few entry points.

I need a few extra, when I started installing them and this was a bargain. Thanks so much.

Easy installation and sync to base.

Great product to purchase

This was a very easy add on. Open the box, pulled the tab, stuck to the door and it was good to go.

I avoided setting mine up for a week because I was worried it would be to techy for me. It was VERY easy to install and get working. The camera is amazing ~ I got a notice on my phone while out of town that somebody was in the kitchen. (It was my adult daughter!) the notifications work!!

This is great for its price, easy to install. Only thing is that the stickers arent that great they loose adhesiveness pretty quickly. Buy your own I possible. Other than that we are extremely satisfied with the product!

Easy to add and install! Totally worth it!

You have to have a base station for them to work at all
