SimpliSafe Entry Sensor (Pack of 4) - Window and Door Protection - Compatible with The SimpliSafe Home Security System - Latest Gen

For me, one of the attractive aspects of these sensors is their ability to stick onto the window or door rather than having to screw them on. But, the sticky material they come with is poor quality. Even though I cleaned the mounting surface with alcohol, several of these wont stay attached to the door oe window. Discovered that the first time in the middle of the night when one fell off the window, setting off the alarm. Unpleasant way to wake up. I figured it was just that one, but shortly after that, another one fell off. Then another. Ill probably have to use the screws to attach them all, since we dont trust any of them to actually remain attached to the doors or windows. Until I do that, we dont even use the alarm system since were afraid of when the next one will fall off. Except for that fatal flaw, the system works fine - I can attest to that after several sleepless nights after false alarms. I would not recommend these until they fix this problem.

Don’t get this system, I ignored the negative reviews and went ahead. I guess when it’s bad it’s bad. And mine is bad. So bad that I have to reset every sensor every single time it decides to “disconnect” at least once a day. Chime “welcome to simply safe” constantly. They sent me a new “cellular modular”. Didn’t fix it. I wish, wish, wish I had spent a little more money on a different system. Feel free to ask me any questions you have. I’ve been dealing with customer support for a while now. Im not an easy disgruntled person but in the writing of this review (5 mins) the system has reset itself 3 times. DON’T DO IT. Do not trust your lively hood/security with this system:

Had no problems setting up and testing any of the components. Had problem with one of the cameras not connecting to the internet. Tested while speaking to one of SimpliSafes technicians and determined the camera was defective. They immediately put a new one in the mail to me. There customer service is very good. Received the new camera and everything works as advertised. Im very satisfied with the system and the price.

Easy to install

Any product made by this company is awesome

Customer service: just a canned list of instructions! The battery door is so snug, that it cant come off unless the sensor is essentially glued off the door -- one still struggles with it to open it with a screw driver or something. Poor plasticky design. The bigger issue: then the Base station (the system) just doesnt recognize the sensor after its battery replacement. Calling the customer service is basically a painful reminder that every time I will have to remove the sensor from the list of devices being monitored, and then add it back. Simply ridiculous product. This is my fifth call their customer service on one thing or the other.. Usually the product works okay, but the pain points are too many. This is much more painful than changing a bulb. As if life should just revolve around fixing Simplisafe issues at home!

One of the sensors was used and wouldnt stick to the door. I had to use duct tape.

Installation is so easy on these. Just add to your simpisafe system and adhere them to your door, window, etc.

These sensors are very easy to install and activate. Sensor will respond to an open entry within one to two seconds. The only issue I see is that once in awhile I will get a device not responding message that will last for a few minutes then it restores itself. The first time it happened I thought it was just a device issue. However this situation happens to various of the 17 entry switches installed.

Very easy to install
