I couldn't resist. Had to order some of them. I'm sure the quality of plastic won't be as good as the official stuff. But I have quite a few bootleg HF figures, and the parts work great for MOCs when combined with official parts. I love the fact that so many of these parts are in colors that Lego has never, and probably will never make.
@Ghosty Aren't those awesome? To me they were worth the price of the figures alone ($15.99 USD including shipping).
Just for fun, here's a random bonus set of super heroes I found on there. Look at these heads! lol
