These things got such bad reviews - that I ordered 3 just to be sure I got one good one (at least they're cheap). I gave them two stars instead of one since, oddly, 2 of 3 of them worked for their intended purpose (a size adapter for my iPhone), though none of them work when plugged into my PC. Hard to imagine this is a very difficult product to manufacture - so I just assume the manufacturer could simply care less...
