The commodity that arrived at first, the movement of the bearing of the rotating scale is very astringent, we sent a substitute as soon as asking for an exchange. However, there is also a catch on the movement of the substitute, and at an angle, it is in a state to read the tick marks by tapping it. Although the price is cheap, since it is a firm making product, I think that it is even better if it is improved.
