Have bought this router for home use, in other words, I'm just doing my own nails, do not have a studio. For this purpose, it is enough. That he sometimes blocked I can confirm also, mainly when it is set to minus. I am but noticed that it runs without errors when introducing the paper until it stops. So used gabs so far no problems. Also it is a bit warm, but this has so far not affected the quality. For a Studio it is not recommended, but personally I'm satisfied. Therefore 4 stars.
