I bought it, tried to engrave with a crooked collet - a convenient tool, then since the nozzle was crooked, the drawing turned out to be unsightly. Smelled a little, warmed up a little, but works well so far. BUY A SEPARATE SET OF NOZZLES, maybe even from a Dremel, and you will be happy. Different pros: A good case at first glance, it doesn’t stink very much, there is a small set of all sorts of cutter disks and pebbles with it. It behaves normally at low speeds - yes, it can be stopped, but it is suitable for engraving. Not as noisy as a dremel. With its cons: A curved collet in the kit + it is also smaller than the socket, that is, it turns out that any nozzle will hang out. Throw out the collet nafig immediately.
