The compressor and tank both work as advertised, the switch seems to cut out a little north of 120psi but that's not a big issue. The main problem with it is the use of unusual thread sizes, if you remove the air pressure gauge the threads on it aren't a standard NPT size, smaller than 1/8\" NPT, and the port on the bottom is M10x1, so if you want to add a pressure relief valve or water drain valve you'll need an adapter.
