I had a brake Buddy that worked great for years but finally died. My wife and I bought a Blue Ox Patriot system and have had nothing but trouble with the system since we bought it. It does not matter what we do it's one bump or a quarter mile before it is "Out of Position". We have been told that our car seat is to soft so we tried using different kinds of material to put a barrier between the seat and the unit which made no difference, When we went to the Quartzsite show back in January a Blue Ox rep told us that the system may be to sensitive. We are currently looking at different systems and will change to something different very soon.
