Review on UHPPOTE Inswinging Electromagnetic Smartphone Controlled by Brent Porter

2/21/17 Updated rating. Initially the magnet came loose after a while as you can see from my email below. After some experimentation I removed the wiring for the trigger and the magnet worked as expected. There must be a problem with the reset button. I'll rewire it and use the wireless fobs if I have to. So far, so good. Installed on a secret door to a secret room. Set up was, as everyone said, cumbersome and with poor instructions. As a contractor, I understand that. Everything works and there is a second button. The only real problem is that after the door is locked and I leave, when I come back a few hours later, for some reason the magnet is released. He did this for several days. As the house is new I know all the electrical work and even put in a backup battery to keep the power going and the magnet not tripping. It didn't help anyone. So now I have a secret room with a door that doesn't stay closed and I can't figure out why.
