The item is too small, weak and useless for practical use. It is waste of money.
Played with the kit few days and measured the chuck which is off center by 0.43 mm although jaws meet as square. For the size of chuck this is huge. The motor constantly produces noise at holding positions and the torque is so week that it can be rotated with two fingers from the chuck side.. Tailstock is the best part, which unfortunately loses its center when extended more than 10mm.
Works really well. Worth the price. Reversing the teeth on the chuck was difficult, but i was able to do it after some jiggling.
