I now have about 5. 000 miles towing with the Prodigy controller and there is an amazing difference from my old controllers. I was using a Kelsy Hayes unit and it seemed to work OK. However I was always fiddling with the gain and angle settings to make them work. This new unit is simple, it just plane works. It was about time for a major leap in electric controllers. I am now a very happy trailer puller.
