I don't think anybody is surprised anymore when poor quality product comes out of China. I dodge it unless it's a Holga camera. It's supposed to suck.
Like John says, it is a pity if it's not usable. I saw a posting of Jim Galli in the galleries that was printed with that Amidol, and it appeared as if he had to jump through both one and two hoops to get to what he needed, but it was usable to him.
The Chinese Amidol works fine for me - the price was certainly right! I don't mind filtering the working developer solution.
