Who in the hell would review this shit anyway, they know it's a clone, but they do it just to be retarded.
Never ever buy a clone, geeez kid.
I wouldn't necessarily say don't buy an R4 though. If you know exactly what to look for you may get lucky and happen to find an authentic one. I did. My sister wanted one and wouldn't settle for a friggin Acekard for some damn reason (She's almost as annoying as this damn kid in the video.). I had to buy an R4 for her and luckily it was 100% authentic. I compared it to my V2 (I've got a broken spring on my V1). It matched 100%.
So anyway, you can find a REAL one if you look HARD. But it's so outdated that it's really not worth it. I use YSMenu on mine though when I use it.
