RMB, can't help you directly, but I have been using the original RVi brake for four years now. Easy setup-- takes about two minutes to go through the tow prep for my car, but of course that would be required no matter which brake system is used. After that-- or actually while the prep going on-- it takes about 30 seconds to set the unit in place, then about 20 seconds for the self test and we're ready to go. Easy setup, easy detach, easy storage. No problems, no failures, very pleased.
