I have these installed on my truck, wife's car, 4wheeler, and all 4 of our dirt bikes. Last year my dirt bike was stolen out of my truck at work. I located it in 15 min. It's the best purchase I've ever made by far. I don't think it's the same company as those you sell. I pay a flat fee one time a year witch lets me locate each of them 3 times a year. Out standing product 4 sure
