This was actually the first thing that I had ever purchased from a TV infomercial...Got it for $45 + about $7 shipping I think? Anyways, works like a charm so far, no issues at all except that our cars don't have a digital fuel level sensor that the UG can pick up on, so you have to manually enter your fuel top ups whenever you do. Not a deal breaker IMO, but a small inconvenience.
