Works well till it doesn't
(Ca) | January 28th, 2020
Lots of cash for this system, but have had a number of problems with it. Blew a couple of shutoff switches and now after just 2 years, the compressor has quit completely. Now it's another 260$ for a compressor replacement that's on me. If I knew it wasnt going to last long, I may have looked at other systems. Now the airbag and horn system is down and I have no choice but replace in to keep my airbags inflated. For the money spent, figure it shoulda lasted much longer. Advertised it could air up large tires and run air tools, but I never did and doubt it coulda handled much more than just air bags and occasional blow of the horn. Shop around.
