Harbor Freight - Gems and Junk

It seems as though the Harbor freight stuff is just kind of a crapshoot on quality. I've had quite a few different items fro HF as my wifes grandfather liked to give me stuff from there for Christmas presents.
I bought one of the aluminum jacks several years ago and it worked a couple of times and then would leak down as fast as it pumped up. I swore I would never buy another but Grandad found out my jack was broke and bought me one just like it as a gift and it has worked extremely well for years. I had similar luck with one of their 4-1/2 grinders. A couple of uses before the guts grenaded. The second one has worked as well as my old Milwaukee. A chop saw was a one time use deal before it melted down. I have a dust collector in my woodworking area and it works very well aside from a switch replacement.
Some stuff is pure junk, anything abrasive, saw blades and drill bits, air couplers, welding wire, etc so I do not even consider those items. I do use some of their wrenches and sockets as my carry along stuff in my cars and they seem to be fairly decent. So my thought is that if it is something I would be upset over if it doesn't work more than once I don't buy it and if it continues to work I am pleasantly surprised!
