Customer Ratings & Reviews

Quality product, easy setup, aesthetically pleasing.

Easy to set up, good range in a house and through walls.

Sorry for the sarcastic summary but like EVERYTHING that I've gotten from Simplisafe, it's easy to install and literally works right out of the box. Well, you do need to remove the paper tab to post the device and you do need to add it to your Simplsafe system and you do need to stick it to the window frame but that's it.

This is a great little sensor that works well and can be used ANYWHERE! Windows, doors, garage doors, gun safes, you name it! You can make each sensor do different things, meaning, one could set the house alarm immediately, the others, such as a door, could have a 15 second delay, while another has a 30 second delay.

We were able to add this sensor to our existing SimpliSafe home security system. It was super easy to stick to the sensor onto the wall and door. The sensor already has adhesive and all you have to do is peel the cover and press against the area you want it to stick to.

We have these on 7 entry doors and use them to trigger secret alerts on cabinets and doors where the babysitter shouldn't be snooping. I've found that the sensors don't like the two components being too close to one another and found a 0.5" or even 1" gap between them yields the best, most stable result. Good quality product.

Very simple good service very easy to set up and use works wonderfully

These are great, very easy to add to an existing system. Cheaper than paying shipping to get from the manufacturer. something I learned, if you are trying to put on a horizontal, sliding window, you can use double sided table on a strong magnet from the hardware store so it will fit between the window panes.

Great entry sensor! Good to know you can get these elsewhere besides the website, especially if you know you need one in a pinch! I had forgotten to order for another window and lucky Best Buy had them in hand! Easy to add and integrate into an existing system!

purchase for my sister, Who complain maintenance comes into the apartment without knocking. easy to install and still working

Added this sensor to my system. Works well with no problem! So easy to set up. I had a fancy, expensive system for years, but this Simplisafe system and accessories are so much better with far fewer worries and a better price!

These little things are easy to mount, and they work very well! And they don't cost an arm and a leg.

These Simplisafe sensors are easy to install and help to keep your home safer by letting you know when the door opens.

I have purchased numerous of these sensors for my simply safe security system and they work great.

Reasonably priced motion detector for SimpliSafe. The reasonable price of additional accessories is one reason I chose to go with SimpliSafe instead of Nest. Of course, the sensor does its primary job of detecting motion flawlessly and reliably, in addition to being affordable and easy to set up.

Easy to install and set up. Connected quickly to the base station and sticks on the window well.

This security system piece is easy to install and made me feel safe knowing my family had someone watching over them when I was gone. This is part of a security system that has free connection to a monitoring service that knows when a sensor is triggered and then calls you to let you know.

We had many issues with our generation 1 SimpliSafe alarm system. we upgraded to the Gen 2 about 5 months ago. what a world of difference it made; no more false sensor warnings. the new style door/window sensors installation, naming, and mounting went smooth.

Simple to add as new or replace broken sensors. Convenient to buy in store instead of on line. Helped to expand our coverage.

Easy set up, works as expected. What more can you say about it. However, if you have one that breaks don't buy a new one. Simplisafe is very good about replacing their sensors that stop working for free you just need to send them the broken one back.
