Customer Ratings & Reviews

Easy install with peel off adhesive backing. The two sensors can be as far apart as two inches and still work.

Slim size and I like the beep it makes every time the door is opened or closed. Decent with subscription

Best alarm system on the market. Simple set-up, highly responsive support, reliable sensors.

As opposed to some other door alarms, this one is very easy to install and annunciates through the base. Also the base does a pleasant sound, can be turned on and off, and doesn’t scare the mess out of you.

Bought these to add to my SimpliSafe system. Really pleased with the price, ease of installation and quality.

Easy to use. Easy to setup with Simply Safe system already installed. Sticky works with most materials, but not unpainted clean wood surface.

Simply safe is very good quality and super easy to add a sensitive to the system.

SimpliSafe excels with their products. Easy to install, and beautifully made. Easy integration with system.

Excellent product! I love my SimpliSafe system, and Best Buy helps me by stocking what I need. Thank you!

I have the SimpliSafe system and have these sensors on all of my windows and doors. They are great and so is the system.

Very easy to set up and is very reliable. It comes with the adhesive so that’s a plus

So far, so good. No problems adding to existing system. My only pet peeve is not with them, but with the base system limitations. When adding them to a room with multiple windows, only the first one gets the "room name" on the test announcements. All others with the same name are listed as "room name #" but simply announced as "entry sensor without the name. It would also be nice to add a custom name for a sensor.

Just what I needed to completed my system . Great quality and easy installation

Totally upgraded from ADT to this wireless system so I could lose my landline and have better control over the system. Everything—sensors, base, cameras—all work together seamlessly. The monthly monitor fee is also less $$!

Worked great and it was very easy to install. I recommend this to anyone who needs an extra room alarm by simple sefe.

After purchasing the main Simplisafe system which I have found is a very worthwhile investment, I decided to pick up an additional sensor for my yard barn as there have been thefts in my neighborhood. I wasn't too sure if my system would pick up the signal as it is in a yard barn 75 feet away from a brick house. I took the keypad with me to make sure it would connect, which it did without any problems.

easy to install and program into simplisafe system. the only issue is that the adhesive did not stick properly to the surface and needed to be replaced

The SimpliSafe Entry Sensor has been working perfectly since I purchased it over a year ago. The battery life is very good as it is mounted on a door that is opened frequently. I have never had a problem with it not connected to the base station.

Great price and easy to install. No tools needed.

Works as advertised. Easy to install.highly Recommend
