We went over this before....there a BIG wast of time and money. Some of the Zetec guys said that it works ok, but from my experience it works decent on large displacemnt vehicals. But its nothing to shout about...nothing worth 60 or 100 bucks thats for sure. This is just my opinion form my personal experiences. Others have had good luck with them. But if it were me, I wouldn;t spend any money on an infomercial.....
I mean come on, how many have been rip offs in our life times?
Good luck with what ever you decide.
