Have never used them. Came close to it but decided to back out. Main reason I did was because they had told me that they had a certain shoe. There was only 150 of those shoes made in the world and they were given to Nike Executives and Sony employees. Well made me start to think of why China would have them. SO that kinda threw up a red flag for me. Plus they only take Western Union and that is just to big of a risk. Chen that works there seems like a nice guy and SWEARS that the shoes are authentic but all of them will tell you that until they get your money and then you don't hear from them again.
I would say that 99% of the Nike's coming out of China are fake. If they are then customes seizes them and you lose your money.
Guy at Nike Global told me that if you buy enough to ship by sea that customs won't bother you but who in the HECK can spend $20,000 or more and trust them with that kind of money.
Wish someone would order so we can all put our trust somewhere...Good Luck
