Covers many pen sizes, but is very loud and makes dirt

I bought this Spitzer over 3 years ago, because I needed flexibility in crayons of my daughter. At the beginning I've used it a lot, even though it is loud.
Toll I found the flexibility in pin sizes and I could tilt in the direction from which I was working. The variable adjustment of the angle Spitz was decisive for the purchase. At the time of purchase I also being able to take it because of its ease thought if I would need it. After tough anywhere but found the surface drill and bits of wood, I did not try it first.

Over time, the Spitzer has become even louder that it's uncomfortable to use it - so shrill and loud as he droning to himself. Conversations or focus on your work, you can forget it. A fact that no new batteries or blades. The latter were also at least 2 years ago still hard to find. After you replace the blades it was marginally better again. Meanwhile, but you have to push down the pins properly fixed so that they are really sharp. This creates a child. Even I do after a few pins hurt fingers.
He is incontinent. No matter how clean I brush him - wherever I place him, I have little air remains. I would probably keep him permanently clean so that the subsides eventually - but then I do not need a pencil sharpener with container. That's why he has rather quickly get a diaper.

I bought a new, no longer battery operated sharpener. For some time this sharpener Derwent is now in the basement and I use it only as a backup if I need times a (!) Until it eventually no longer move. Normally I would have cleaned and inserted him. But this screeching something I can not resell a clear conscience.
