Não é um bom cubo

First things first: It turns EXTREMELY bad. I thought, I will brake it, because it was so hard to turn.

It 7s a 1x2x3, it's small (about 5.5x3.5x1.5cm).
The "red" colour opposite yellow is something like brownorange)

The size and the colour is not the problem, but I say it again, it turns absolutely horrible.

I bought many puzzles from this webstore, but this is the worst.
