I know this may be a case of “you get what you pay for” but I had purchased this set last year for $50 and they do work. My issue was I never set the +/- well enough so on a trip when I would hit a rest stop, the air in the tire would decrease too fast and trip the machine showing a tire leak. Plus with the dually, no way to keep an eye on all (6) tires. Of course my class c is smaller than most so no idea how longer wheel bases would affect performance. I don’t know, probably more cons than pros, especially since they are now only $30 regularly but I just love a deal so please don’t shoot the messenger
