First Experience with a Prodigy Brake Controller

I went through a couple of Voyagers. The first one just got weak so I bought another.
I finally tossed the second Voyager after having to stop on seriously steep hill (a detour) and found it didn't work in reverse. I had to stand on my truck brakes to hold it from rolling backwards down hill.
Finally got the P2 and it's not only stronger but it's activates much more naturally. And works going backwards.
