GEPersonal Security Alarm Kit, Includes Deluxe Door Alarm with Keypad Activation and Window/Door Alarms, Easy Installation, DIY Home Protection, Burglar Alert Pack of 1 45117 1

No funciona si lo colocan en puertas metálicas o de herrería, ya que funciona por medio de magnetismo y con el metal pierde la sensibilidad de sus sensores, me imagino que con aluminio y otros materiales no magnéticos funciona bien. Lo solucione colocando dos cuadros de madera de 2" para separar los sensores de la puerta metálica donde pensaba usarlos

Easy to install. Sensor can be installed on either side of the door alarm. The self-adhesive stickers are located separately inside the package alone with the instruction manual. The alarm can be "unclipped" from the mounting bracket to replace the batteries.

Easy setup! Changing password was easier than I though it would be. I had to change the tape because it wasn't sticking to my unstainted/unpainted door.. Only downside to this product is that It's not animal friendly (loud) no matter where you are In the house it's ear popping..Yes I recommend this product but not for pet owners..

Funcionó muy bien, hasta que un día que abrí la puerta y no desaactivé la alarma a tiempo, esta sonó todo el tiempo y no servía para nada la clave mara desactivarla, tuve que arrancarla y romperla para que se callara. Eso es un error gravd de su diseño.

We had trouble getting this to work properly on our front entry door. We finally called service and they told us that it won't work on steel doors with putting some kind of barrier between the product & the door -so we have a piece of cardboard attached under it -works but looks bad and not too stable. This product would be better with a light on it to signal when it is armed -we don't always arm it when we are home and it is impossible to know if it is armed without either opening the door or putting in the code.
