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.

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.

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

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.

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.

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

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

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.

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.

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!

This sensor was added to my SimpliSafe system as I omitted one when building my house’s system. Although I’m technically adroit, I was impressed with the ease by which the system was installed, configured, and expanded. The sensors are easier to install than hanging a picture. One word of advice, when selecting the side of a window where a sensor will be mounted, mount it with the test button facing up and leave room for the outer case to slide off for battery replacement.

Easy to set up and use. Works very well. Good value.

These were additional sensors that we purchased for our home. They are easy to install and set up. Small so they don’t take you much space and they are barely noticeable. They are reasonably priced, so it’s inexpensive to cover every window and door. Since these were in stock there was no wait and were purchased on line for no contact pick up. Soon we’ll be adding another camera to our system. Thanks for great service

These sensors work so well! I have an older house and the bundle I bought didn’t have enough sensors so I added one to my purchase. They sit perfectly on my front and back doors as well as against the windows.
