Never buy a parachute from Harbor Freight.
I have some of their stuff, some of it is OK, some of it is bad to the point of being dangerous. The question to ask yourself is this - "If this fails, will I get hurt?" If the answer is yes, buy somewhere else for a little more money because hospital bills are really, really expensive.
I have a 4 by 8 folding trailer from them, great value even though the hardware isn't metric, English or Whitworth. (Ever see a 16.5mm socket? Me neither.)
I have a cherry picker engine hoist from them, it works, but I am very careful not to put myself or anything I care about under it.
I have a motorcycle lift which almost guillotined my hand during assembly - they don't warn you about it. Be careful.
I also have a large box of now useless cordless drills with bad batteries. The batteries aren't warrantied even though the drill is, and after a year of so, you'll hear "that style is discontinued and unavailable".
Would I trust my life to a set of Harbor Freight ramps or jack stands? No, I don't think so.
Best Regards,
Mike/Florida
