Crime stopper has been around for a little while. But like other company's such as Code Alarm, black widow, and a few others out there, they are a little shaky. I would advise to stay away from a smaller company like them. Get an Auto Page or better yet any DEI alarm like Viper. If you buy this thing and that shop goes out of business next week is there another local dealer who can work on it for you. Plus depending on which system your getting from them $500 is a little pricey.
I must sound by now like I work for DEI or something.... I don't.......lol
