... poor quality stuff breaks easily...
in my... well, september 2011 till december, the crappy mouse which came with the hp computer broke, left key n right key don't press properly =/, from january this year till now, i went through 4 pen-heads on the tablet =D, since it keeps rubbing the point away xD!!
(then a bunch of crap from other games... broke keyboard twice (arrow keys busted cause of pressing em too fast...), computer fried once, (cause of keeping a game open to open shop for 4 months...) xD
note of advice...
don't buy stuff from chinese flea markets
