i did mention that it was from china, haha, that's why i ask you guys to check out for me whether its genuine, neway, for RM100, who wont want it

But the fact is you don't get 8gb for RM100. It's a fake, the real size once you repartition it might only be 1gb or even lower. And data you write into it will take a really long time and when you try reading data from the drive, corruption occurs, who would want it then??
