The thing is inexpensive, in the best sense of the word. For soo little money the cutter may be nothing special, that should be clear to everyone !!! BUT: Who can tinker a bit and a little knowledge of mechanics, which can optimize the thing quite well. I needed a piece of scotch, a file, drill nit 3,5er Metal drill and a corresponding screw. Hnterher wobbled nothing. I am satisfied because I so wanted schneden a few round glass panes with the product, but it has gerreicht. A useful unites precision has become errechbar to my tinkering. The other, sometimes very critical opinions, but I can understand. And the thing stinks the first few weeks as the "pig" ...! ! ! So nothing for "bedroom"
