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.

Purchased for Garage Door Sensor. See pic. Works great

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

Simply safe products are much better than big brand alarms

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

SimpliSafe alarm system entry sensor to replace old one.

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

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.

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.

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!

Love simolisafe and the quality of their product. Olug and play installation and 24/7 monitoring

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

Already have an installed SimpliSafe system so just needed to ‘add on’. Especially liked the fact that BB offered the option to buy additions - thru SimpliSafe, minimum order is 4.

I purchased these for windows and doors to work with my Simplisafe system. Included are small mounting screws or the option of an adhesive backing. The screws were not going to work on my surfaces (mostly metal) so I tried the adhesive. The adhesive did not stick well to metal. I purchased Velcro and cut to fit the backs. This solved the problem and they are firmly adhered now. The sensors work as described and the base signals when a door opens. While I was installing these Simplisafe was alerted and called me as I inadvertently did not disarm while doing this! They work! Simplisafe helped me change the settings while installing so repeat calls to them did not occur!

I purchased SimpliSafe Security System and needed sn extra sensor for front door, I purchased this one and i am extremely happy and comfortable knowing thst whenever my front door is opened my SimpliSafe System alerts you. No more surprises from unexpected guests or visitors that just walk in.

I love simplisafe! I love their concept of being able to build your own home security system at your own pace and you can purchase different items when needed without the hassle of being in a contract. The entry sensor works perfect for our windows!
