Harbor Freight - Gems and Junk

Well, regarding consumables, I have used many of the H.F. 3" cut off wheels and find they last a good while - at least as long as the name brands. I have the stud gun, it is good although the slide hammer that came with it was pretty cheap.
I do not like their quick couplers for air line, they don't seem to last long and I don't seem to be able to get the exact match the next time I go in.
