Customer Ratings & Reviews

Easy to set up, good range in a house and through walls.

We have these on 7 entry doors and use them to trigger secret alerts on cabinets and doors where the babysitter shouldn't be snooping. I've found that the sensors don't like the two components being too close to one another and found a 0.5" or even 1" gap between them yields the best, most stable result. Good quality product.

Simple to add as new or replace broken sensors. Convenient to buy in store instead of on line. Helped to expand our coverage.

I’ve had Simpli Safe for 10 years, and the quality and reliability of there products are unmatched.

Great entry sensor! Good to know you can get these elsewhere besides the website, especially if you know you need one in a pinch! I had forgotten to order for another window and lucky Best Buy had them in hand! Easy to add and integrate into an existing system!

Added this sensor to my system. Works well with no problem! So easy to set up. I had a fancy, expensive system for years, but this Simplisafe system and accessories are so much better with far fewer worries and a better price!

A great and safe addition to our simplisafe system. It is easy to install and keeps us safe.

These are great, very easy to add to an existing system. Cheaper than paying shipping to get from the manufacturer. something I learned, if you are trying to put on a horizontal, sliding window, you can use double sided table on a strong magnet from the hardware store so it will fit between the window panes.

These are great, easy to apply and work. The whole simpli safe system is great

Works as it should. Same price as from the manufacturer. Easy to set up

The little things count too. This entry sensor will provide peace of mind to me and my husband when we install it at a door or window in our new house to alert us of intruders. We will definitely be purchasinh more soon.

We had many issues with our generation 1 SimpliSafe alarm system. we upgraded to the Gen 2 about 5 months ago. what a world of difference it made; no more false sensor warnings. the new style door/window sensors installation, naming, and mounting went smooth.

Easy set up, works as expected. What more can you say about it. However, if you have one that breaks don't buy a new one. Simplisafe is very good about replacing their sensors that stop working for free you just need to send them the broken one back.

Reasonably priced motion detector for SimpliSafe. The reasonable price of additional accessories is one reason I chose to go with SimpliSafe instead of Nest. Of course, the sensor does its primary job of detecting motion flawlessly and reliably, in addition to being affordable and easy to set up.

This security system piece is easy to install and made me feel safe knowing my family had someone watching over them when I was gone. This is part of a security system that has free connection to a monitoring service that knows when a sensor is triggered and then calls you to let you know.

Simplisafe is the best security system. Its easy to set up and no long-term contracts, no over priced equipment, and the best is that you have FULL control over the entire system unlike ADT.

So far so good, works good with the homebase. I bought a few , they all work well so far. Easy to set up.

Bought it as a replacement. Easy to connect wirelesly to the Simply Safe app.

We had an old security system from a big company and the customer service wasnt very good. Simpli Safe has been fantastic and I love that I can buy extra sensors at Best Buy instead of paying a lot of money to a big company. It is a great system and very easy to install. We love it!

This device was very easy to install - it uses removable adhesive strips for mounting. It is very tolerant of the spacing between the magnet portion and the detector portion (up to 2 inches). I have installed 3 of these and have not had a problem with any of them.
