Window and Door Magnetic Sensor Anti-Theft Security Alarm Set (3*LR44)

Pros: Buen acabado, tiene aspecto de ser plastico solido y resistente. Es mas pequeño de lo que parece. Hace mucho ruido, el nivel de sonido es alto, lo cual para este tipo de alarmas, es deseable. Funciona perefectamente.

Cons: Es facil de apagar por el ladron. Solamente con apagar el interruptor. El compartimento de las pilas esta muy duro de abrir.

Other: Cumple su cometido a la perfeccion.

Pros: so they sent me one it was defective on arrival: they replaced it without a hassle, i received my new product without having to re pay, and am really happy with it. i put it on my window and it fits nicly, if i open it a few cm it will not ring which is great, and its extreamly Loud

Cons: none that i can see, possibly a cheap build, but for 3 bucks i cant complain. it can be disarmed if the culprit knows where the on off button is it can also be disarmed by placing a magnet on the side of the device.

Other: its great. thise things can be priced at usually about 15$
