The machine is good. The set includes a lot of nozzles and a flexible collet. Who wants to buy - take it, you will not regret it. But carefully check it when buying: I chose from two copies. There was a rattle at low RPMs. The second one was normal. Different pros: One of the best non-professional engravers. Lots of attachments and a flexible collet included. Cons: Overheats (although the instructions say so: for 15 minutes of continuous operation, then a break until it cools down)
