I have many Summit brand parts and "things" - so far the only item that I'm not fully satisfied with are the valve covers currently on my engine. They have a sub surface corrosion that will polish out if really aggressive on my buffer wheels, but the usual polishes wont clean them up - so they'll go to a swap meet and I install my new Billet Specialties pieces. Chinese made and probably cast from recycled beer and pop cans

Their tools are IMHO for the most part comparable to Harbor Freight. OK, but not for semi pro or pro hard use plus too expensive if you factor in shipping.
