It's a rebranded Smittybilt compressor. I've had my SB one for 5-6yrs now with no issues. Takes no time to fill up my 33s, wasn't a slouch filling the 34s on my F150 either.
At a recent outing, I filled my 4Runner tires (33s), my wife's Taco tires (31s), another couple's 4Runner tires (31s), and our excursion trailer tires (31s) in under 30 mins. Didn't give the compressor a break, hooked up my manifold from one vehicle to the next, aired everyone from 16psi to 33psi (except my 4Runner, it went to 38psi). Mine is mounted under the hood, so it was doing it next to a running engine on a typical Louisiana day (over 90F & over 60% humidity). It never cut out, slacked up, or even changed its tone, just kept pumping until I told it to stop.
