yep it is the best ...but i think in the long run it will save you alot of $$$$$... my brother has one in his car and when i take his car out (once in awhile) I speed like a bat out of hell B/C he's got a bad ass car anyways back to the point it's saved my ass many a times ....And i promise you it WORKS . So just invest a little bit more now and save your self some money in the long run
