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

    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.

    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.

    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!

    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.

    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

    Was actually easier to order via Best Buy than going to SimpliSafe. This unit is also NEW, units replaced by SimpliSafe are always Reconditioned. Will keep this as a backup for future sensor fails.
