I've posted some great things for a great deal at Harbor Freight, I have some things that are just horrible also:
Mechanics Stethoscope - FAIL - doesn't stay on your ears because the metal "spring" doesn't spring" whole thing is cheap and feels like it will come apart any minute. But it does work.
Heavy Duty Chain Breaker - FAIL poor design does not hold the chain like other designs, and just doesn't work well.
Hand pump vacuum brake bleeder - FAIL but can be re-worked to PASS I got it a while ago and just had to use it recently. Would not hold pressure. Took it apart, cleaned it all up. Put a little silicone.... better... was still leaking. Changed the bleeder valve (auto tire type) Now it works great!
8 inch benchtop drill press - FAIL - poor run-out, vibration and cheap stamped metal stand and table bends and flexes. Horrible! Useless dim light, holes are not round - getting cleaner holes with a hand held drill... that's sad. Not sure how it fix it... might be a total waste of money.
Recently I've noticed their prices are getting higher so much that we can find better deals for no-name Chinese tools are other stores like: Menard's, Home Depot, Advance Auto, Wal-Mart. It's too bad. I miss some of the stuff they used to sell like their carbide tool & die grinder, rotary table and other machinist tools. Not sure what market they are going for but I personally do not like the changes. Higher price and worse tool/selection.
