Customer Ratings & Reviews

Cheap and easy to install. Works as advertised. Old one broke. But cheap enough I’m not sad.

I have one on every window and door. They work great.

Good alarm system love it would recommend to anyone easy to enstall

I needed some additional sensors for my new house and picked them up at Best Buy. They're easy to install on windows and doors and connecting them to the Simplisafe system is a breeze. My whole house is now protected.

super easy to set up, works great. Easy to connect to my existing simplisafe setup with easy integration into my app/settings. Better price than buying directly from simplisafe too.

I needed one more sensor from what came in a package. Best Buy had it in stock and it was easy to find in the store. Self installation steps are easy to follow. Unit has worked reliably to date.

Super easy to install! I feel a lot better having this alarm system in place.

Simple solution for home security. Bought this as an add on to our simplisafe system. Work great, easy install and setup. No complaints

Works great with the alarm it chimes anytime a door or window is open. On the application it notifies you which door or window is open.

Very easy to install. Thought adhesive would be weak but is actually pretty good.

We have several of these sensors on doors and windows throughout our house. We always know when a door or window opens from the audible chime from the system. Very pleased with the entire system. A+

These were easy to install and add to my SimpliSafe system. The only problems were installing the sensors on metal. We had to insert an insulating later like cardboard between the sensor and the metal.

Very easy to install and compliments one of the best alarm systems. Also very reasonable accessories. Many other options available

Needed to add another entry sensor and this one works as well as others. This system continues to make our home and shop secure.

A simple and easy to install entry sensor to existing SimpliSafe security system. Though a bit expensive compared to buying a whole package, but still worth it as an add on.

Simplysafe was the best decision I have ever made to feel safe and secure. Bought this to incorporate into my existing system! I recommend Simplysafe for all your home monitoring needs!!

Needed to replace two and it was nice to go to the store and get them right away no waiting for them to arrive by shipping. We love the product .

Works great! Love that i dont have to drill holes into my door frames and window frames to install the sensors

Sensors are so easy to install and I like that they are attached with removable strips, making relocating or replacing without messing up your surface. So far, doing what they’re designed to do.

I recently bought three more of the window alarms when Best Buy was having a sale on them. Easy to add to existing system and they chime when you open a window or door so you know they are working
