The material and the workmanship are good. Unfortunately, it lacks a German operating instructions, especially with regard to the hygiene of the article I would like to see this, and he's also a little big for a start, but that may indeed be the case only with me. I think a beginner man should leave it at 2.5 to 2.8 cm, and start with this toy a little later. For the lack of instructions and the note in the description of "easy to implement" ever a star deduction.
