Does work nice. Works just like a realy high end one ppl cant even touch my SUV without it going off. The door triggers are really nice too, I love it. The only thing i wish it would have is a sock sensor turn-off in the remote. Other then that It's sweet for the cost. Saved my electronics a few times so far its the best i have owned. The LCD remote doesn't show what part they're trying to get in to or what part was hit or whatever. Like i said its really nice for the cost and I would buy it again. I can arm it from over 300ft easy i know that for sure.
