I have one as well and immediately replaced the power supply with one that has a dial to act as a speed control. My only gripe is that it only has a power drill chuck and not one that can grab 2-3 cm diameter cylinders from the outside.
It would need a longer tool rest reversed so it is closer to wood for safety and better tool control - if actual wood turning tools were being used. Best not to leave chuck key in chuck. "Center it the best you can..."!!!
