We used a Brake Buddy for our Saturn VUE from the outset. There were times when the exhaust brake would downshift at the same time as I used the brake. This would exaggerate the stop and cause the Brake Buddy to lock up the toad brakes and we would drag the toad to a stop. The final straw was when we flat-spotted a brand new set of Michelins. We switched to the AF One system and have not looked back. Very easy to hook up and proved itself on the first trip when some idiot coming out of a rest area decided to squeeze themselves into the small hole between us and the car in front of us. By the way, AF1 gave us a $200 credit toward the purchase of their system. Not sure if they are still offering that.
