When I lived in China there is so much fake stuff everywhere, selling USB drives with capacities that far exceeded anything manufacturers were even listing at the time... things like a 1TB Kingston USB drive for peanuts... they'd plug it in and you'd see that amount of capacity too... then i asked him to format it for me and he refused lol
It was fun to wind them up and have a laugh but they have so much fake crap i'd never buy anything from them remotely via ebay - even when i was over there they'd try there luck.
I suspect Paypal protection would cover you, but if you're looking at stuff which you think might be junk, then 99% chance it is, so dont waste your time... you're never going to end up being pleasantly suprised, that I will assure you of!
To give you an idea of what its like... where I lived, i had 3 "DVD" shops close by... each of these were huge... everything they sold was pirate... nothing was legit... its just how it is over there.
In Shanghai, the main shopping street is Nanjing road... Peoples park is in the middle of this road... one way is all the fake stuff, the other is all the genuine stuff.... now with both being able to be sold in shops so close to each other, i'd never trust the genuine stuff either!
