The Prodigy is a cool tool! Once hooked up and pulled the horse trailer a short distance down the road. Kept getting a wierd symbol on the Prodigy readout as I was moving down the road and knew something was up with the brakes. Wasn't too worried about stopping the trailer without its brakes as it was empty and my destination was close. Pulled out the quick reference manual and found the wierd symbol was an error code telling me I had a bad ground connection. Sure enough, my trailer ground wire had broken and it was getting a partial on-and-off ground through the hitch ball.
I like it for my occassional use!
