Customer Ratings & Reviews

Battery lasts year on windows and about a year on a door. Easily replaced when they run out. Good small profile product.

Great sensor to add to my extra doors in my house.

These sensors are easy to install yourself and connect to your base station.

We have an entire system but needed another sensor. For whatever reason it ended up barely hanging after a week. I had to get new double stick tape to get it to stay up.

Simply safe products are much better than big brand alarms

Purchased for Garage Door Sensor. See pic. Works great

Easy to install and setup. Great value. Great product!

Easy to set up and use. They work good on doors as well as windows.

clean design with easy double face tape mount .it will work with offset mount on slider about an inch of difference .Wish it had door chirp option it is alarm on or off but still good

Well made. Strong magnetic sensor. No problems. Each unit comes individually packaged with 2 screws and a backing tape attached.

SimpliSafe alarm system entry sensor to replace old one.

These are the same ones you can get on the Simplisafe website but at a better price. They come with batteries already installed and hardware is included if you want to mount them. I just use the sticky pad on the back of the device to put on doors and windows so I don't have to drill holes in my wall. Great price and they work great!

The sensor was easy to find, and the purchase went smoothly. Easy to install, and has been working well since installed.

simpli safe is a reliable and easy alarm system to install without consulting a professional. the various sensors and sirens are very simple to install yourself. the sensors for entry are very well made.they are highly dependable. well worth the price of the system.

Absolutely love this system. Would recommend to everyone. The app is so easy to use. Had a bit of difficulty getting it to line up. No problems since then.

I've been a SimpliSafe user for 16 months and was pleasantly surprised to find that I could order these through Best Buy instead of SimpliSafe directly! The cost is the same, but I'm an Elite Plus member so shipping was free and SO FAST!! Purchased three additional sensors and just like the all of the SimpliSafe products, incredibly easy to set up and connect to my system, everything you need to set them up is included. For anyone on the fence about a Home Security system I couldn't speak more highly about the entire SimpliSafe experience and service. It couldn't have been any easier to set up, insanely affordable, and customer service has been great! The dog set off the alarm once and it's the only time the alarm has gone off (knock wood) and as advertised they called me immediately and it was fine.

Easy to install. Nice looking sensors that are small enough that they don’t interfere with anything. They work great with the hub.

As the title states, this entry sensor is a breeze to install and to use. The only complaint I have is that the adhesive strip on the back of the bigger half, is a little small and weak. HOWEVER, they include extra adhesive strips in bigger sizes if you get these with the entire security/camera packages. If not, you can always buy command strips elsewhere quite readily. You can always use the included screws as well!

I have the whole SimpliSafe system but needed an additional sensor. Best Buy had a lower price than the site for SimpliSafe. So I purchased it along with a 4 year warranty. Couldn’t be happier! Been happy & feeling secure for about 7 years now. Great & thorough customer service reps!

Very good product and was very easy to install. I would purchase item again when needed.
