Customer Ratings & Reviews

Very good product and was very easy to install. I would purchase item again when needed.

I purchased these for windows and doors to work with my Simplisafe system. Included are small mounting screws or the option of an adhesive backing. The screws were not going to work on my surfaces (mostly metal) so I tried the adhesive. The adhesive did not stick well to metal. I purchased Velcro and cut to fit the backs. This solved the problem and they are firmly adhered now. The sensors work as described and the base signals when a door opens. While I was installing these Simplisafe was alerted and called me as I inadvertently did not disarm while doing this! They work! Simplisafe helped me change the settings while installing so repeat calls to them did not occur!

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.

SimplySafe products are highly reliable security solutions that are designed for easy installation, allowing users to set up their home security quickly without professional assistance.

We have had these for a while now. We have them on doors and windows. They work extremely well. If they die or even get low in battery, the system tells you and you can easily and quickly change the battery and be back up and operating.

I love simplisafe! I love their concept of being able to build your own home security system at your own pace and you can purchase different items when needed without the hassle of being in a contract. The entry sensor works perfect for our windows!

very good price for sensor protection. Good brand and easy to install.

Easy to add these in as they are needed in your home

SimpliSafe is a great security system and it was easy to install. We are mainly using window and door sensors (large dog causes problems with motion sensor) and they work well. The only problem we've had is that a couple have not stuck securely to vinyl frame windows and doors with the provided tape. After one fell off a door, setting off the alarm at 3 am, I decided to screw the sensors into the frames. I haven't had any problems since then.

Purchased this extra sensor for a system that came with everything I needed but an another sensor to protect a window. Easy to pair and install depsite it not being pre-paired with the system like the included sensors. They are small and nice looking enough. Highly recommended for the low price to add them to every window in your home.

Love simolisafe and the quality of their product. Olug and play installation and 24/7 monitoring

The Simplisafe entry sensors are very easy to set up. From the keypad, the app or the website, you can edit the names and they are fully customizable as for the different alarm stages. I test the whole system on a weekly basis and they work flawlessly.

These are easily installed and have a long-range and supposedly good battery life. Before I purchased I asked if it worked with Google. The answer was "Yes, YoLink door sensor is compatible with google assistant. You can use Google assistant to query the status of the link door sensor,

I already have Simplisafe system at home and wanted to expand the security to a few more doors. This door sensor allows for easy self install and easy pairing to your system. The sensors also allows for a bit of wiggle room too so the gap between the door magnet and the actual sensor can be an inch and maybe slightly over.

I have had great experience with SimpliSafe these contacts have been in my home for over a year now and they operate flawlessly I was a security director so I know a lot about these Hammer systems and I would rate this system up there with any of the well known leading commercial brands.

Purchased one of these entry sensors for the shed that I have in the back yard. When I originally ordered my system it came with 4 of these which I used around the house. I had a brain f*rt and completely forgot about protecting the shed as well. I was getting ready to order another through Simplisafe but wondered if Best Buy carried them because I had seen other home security products there before. Well I did a quick search through the app and lo and behold they did have them. I ordered one for curbside pickup in the evening and picked it up the next day. Install was easy just like all the original sensors were. Now my shed is protected like the rest of the house is. The range on the sensors is great btw. I don't know the exact distance the shed is away from the house but it is at the far end of the backyard and the homebase picks it up no problem. Definitely would recommend getting these through Best Buy instead of ordering online through Simplisafe.

Simplisafe is a good security system. The door sensor is very easy to install, and does its job. It does not need to be hardwired into the system, and it connects quickly to the base station. Very convenient

Easy to install with the attached sticky pads. Not sure how long the batteries last. Can be mounted in various orientations, and dont have to be as close together as in the picture to function correctly. Can also be mounted at 90 degrees to each other and still work correctly.

Simply safe are a high quality product. 2 minute install, adding to base station is a snap and sticking these sensors up is easy.

These sensors work so well! I have an older house and the bundle I bought didn’t have enough sensors so I added one to my purchase. They sit perfectly on my front and back doors as well as against the windows.
