The gears are biting hard, there is no smoothness at all. It moves in jerky motions with strong jerks. Delivery is very long - more than a month.

Moreover, I took different sizes and everything seemed to be made in a basement. The gears were not lubricated; even after lubricating them and running them, nothing significant happened - the sticking remained. I won't buy here again.
