Several catalogs that used to sell these, and had a liberal return policy, no longer sell them, because they come back when the buyers realize they are no good.
If you want to know what factory conditions are like in China these days, watch a documentary called China Blues. (on PBS). It was about a blue jeans factory. Girls living in dormitories (some as young as 14),away from home, working 17-18 hours a day (no kidding) -- and no overtime pay of course. Paychecks get delayed, their food and lodging gets taken out, pay gets docked for this and that. Horrible working conditions. As I was watching it, I was thinking, Here this is supposed to be a "Communist" country and they are perpetuating the worst of "Capitalism" (because one person owned the factory and was making all the money.). It was like conditions in the US 125 years ago, before there were any labor laws.
