Customer Ratings & Reviews

I needed just one more glassbreak sensor to finish my alarm setup. I didn't want to wait to order it from Simplisafe and I didn't want to have to pay for shipping. So I bought it from Best Buy at the same price. Along with an 8 pack of AA batteries, I was able to get free shipping, which sold me. I do wish that Simplisafe would give better guidance for mounting position and adjusting sensitivity. But overall I am happy with them.

Great price. Super easy to install and setup. Unfortunately, there is not a good way to test it to verify how it works. Don't want to break something to see if it works so I will just have to trust it.

We have a lot of glass areas around our new place so it was necessary to add these sensors to our Simplisafe system. We maxed out on the sensitivity. I've seen reviews that talk about false alarms but we havent had that issue. So far they have been great with picking up tile break during demolition of our bathroom (this is in the adjacent room/wall).

Bought this for my basement windows and door and it works

I added this to my rear balcony as additional protection to my simply safe system. Installed in no time and easy to synchronize to my existing system. Will probably add one to front area of my home to complete my interior security. Simply safe makes a great product and at a very reasonable price and no longer have to pay high hard wired prices for my security. I figure I am saving 50% off of what I used to pay.

I have not had one of these falsely triggered by lighting/storms. They were easy to pair with my base station. They have a clean modern look and were straight forward to mount. It is recommended they face the window/s they are protecting and be I believe within 10-15 feet of the window. The look is modern and clean. Unit is a nice shade of white.

Easy to place, synced right up with the keypad. Took more time to figure where we wanted it than to get it set up. If you already know where you want it less than 3 minutes and done. May need another. It is, as most things these days are, all plastic.

These are just as easy as the window/door sensors to install. Although, I wish it had screw holes like the window/door sensors have in case the adhesive on the back doesn't stick well. But I don't think that warrants a knock on stars. It still sticks to the wall and is easy to setup. I haven't broken any glass around it so I am going to have to assume it works as it should.

Haven't had a real test case for this and hope that we don't need to have one, but its great to have with our large front room window. Easy to install, but requires more precise location than other sensors from Simplisafe due to resonance of breaking glass.

Bought it as an added security for window/door glass breaking. Easy to connect wirelessly to the Simple Safe app.

SimpliSafe is great and their add on components make it easy to adapt your system to any stress done in your home! Sensor is light and blends in with any decor.

We purchased the Glassbreak Sensors for our SimpliSafe system as an addon to the original system. These little devices are easy to place wherever you need to monitor glass breakage in case of trouble. They are wirelessly connected to your base system and provide additional security. We are happy with our purchase and would highly recommend if you have a lot of glass to monitor.

Another great accessory for the SimpliSafe system. So easy to use. Just pee and stick. Communicates with the base station with a click of a button.

We added this to the Simply Safe system because we have a sliding door off of our kitchen that leads to the backyard. This gives us peace of mind that all points of entry of our home are protected, including our glass patio door.

Just installed SimpliSafe. Easy to setup and insta as stated. Works well wish it worked with a phone app without the expensive monitoring.

Easy to install. Works well with the app. Style is not too intrusive.

It detects the sound of breaking glass! Not all windows have an alarm so this makes up for all the rest.

Easy to add to an existing system, but don't have a lot of extra glass to break to test sensitivity and range.

Extremely easy setup. Pull the battery tab and add it to the keypad. You need to adjust the triggers in the master online portal, bit thats easy as well. Note...YOU NEED A SIMPLISAFE SYSTEM FOR THIS TO WORK. .(I have read the lock and doorbell reviews and some people just don't get that these are additional pieces)

I've had this for over a year and seems to be working properly. Thankfully I haven't experienced it detecting a break-in but presumably it would work as expected. Recently after 18 months I got an alert that the battery needed replacement. I suppose that a nice feature. I changed the battery but was surprised that it tested still good. Curious that it seems so sensitive about the battery strength but better safe than sorry.
