> 3 dayDon’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:

> 3 dayThe setup is so simple, I had my 6 year old do the system. Do not let these little devices fool you, mine work to perfection (obviously not all will work as there are some that wont work due to factory production). I cant comment on the glass break because that would require me to break my window. If the mode is off, you will hear a chime telling you the door(s) or window(s) are opened. I will tell you be careful removing the piece to install a new battery. Too much force can pull off the paint or break the sensor. Just FYI

13-04-2025I guess these new generation sensors tend to fall off. Mine fell off in the middle of the night, causing all sorts of rukus. Luckily I was home to disarm the system and hopefully not wake the neighbors. Now I had to buy nano tape to re apply them.
