After our sharpener has (with crank) passed away, we opted for this sharpener, because he can quickly and sharpen many pencils easy - and all major sizes! My oldest son (6 years old) times very (very, very) happy and much. Only with crayons. Therefore, it is about 20-30 (mostly) non-ferrous and pencils (schmale- Standard and thick triangular) who want to be sharpened every week - and this pencil sharpener is doing it perfectly. For about 15 pins of the refuse container is sufficient - then needs to be emptied. Sharpening works well (although not perfect - I think it is up to something big constantly grilling or sharpeners) - but once you get the hang of the works! Sharpening very good and very fast. How many have already written, the Spitz degree can be adjusted (very good, because otherwise at the pointed pins to the top are immediately broken while painting). This part is quite noisy. I had the function (sharpening of different pins) and the important angmessenen at a price. After about 3-4 weeks (ie 100 pins sharpened) - and the pencil sharpener works! Still with the first set Baterrien (no batteries - not tried with batteries). I'm very satisfied - here the true price / performance. An improvement would be good or somehow an accurate indication of the replacement blades.
