لا ينفع السياره بعد غلق الابواب ، ينفع دراجه فقط بسبب صوته المنخفض

Of course it doesn't compare to a build in car alarm, but its a great cheap option for extra security. Works perfect, but the alarm sound isn't that loud from inside the car. Enough for me though, as my car is parked in front of my apartment.

Alarm works really well. Super easy to arm/disarm with the included remote. I put one on the inside of the garage roller door in case of jemmying. Can arm/disarm from the outside through the metal roller door! Only downside to this alarm is that the battery door doesn’t have a screw in it to stop it being quickly opened and batteries removed if alarm goes off. But easy fix is to wrap some tape around alarm to make it difficult to open in a hurry. All up, very impressed! Would highly recommend. And battery life seems to be great but have only been using it for a few days so can’t really comment yet. Super loud for it’s size too.

I had to find a reasonable car alarm for my Ford Escape. This alarm has a loud siren and works whenever a leaf, anything touch this car. the price was only 15.00 which I was skeptical at first but it uses only 2 AAA batteries and I'm telling you, this alarm is loud and very clear. when you open the car door, the alarm shrills loud until you push the alarm to cut off. your ears cant handle this loud noise. My car is sensitive when its brushed against or even when the wind blows hard ! I feel secure now that the neighbors can see and hear my alarm is set

Bra ljud och går igång som den ska

Perffekt !
