Wow, that is really awful, and as a V-Cube owner, it really angers me, just like that Lanlan rubbish that costs $15. They even stole the packaging, heck, they even stole the slogan. :fp
I would definitely not call it a V-Cube killer. V-Cubes are more expensive than knock-offs but there is a reason for that; they're of supreme quality, and knock-offs will never be of the same quality as a genuine V-Cube.
