Probably I just had bad luck, but when I tried to sharpen the thick jumbo pen a guest child, broke off a large piece of mine and damaged apparently the machine. Pins could be then no longer sharpen correctly and Fräsrolle came not to all sides of the pin.
But the customer service from ACME Europe helped me once more. Under their guidance, I tried to fix the problem himself. At first I was skeptical because I wanted to lose no guarantee. But I was assured that the device I - should I not be able to resolve - can send it and it will be repaired, even if I had previously poked around with a metal pin in it. ACME Europe is very important to the customer.
said and done. I could not repair the damage itself, so I sent the unit over New Year. Already on the third day after I received the order confirmation Beriebsurlaub for a new Spitzer and a very nice e-mail, with the contents, we regret the incident, I would receive a new device and you'll be the cause go to the bottom. That's what I call customer service!
Incidentally, I later found that several jumbo pencils branded JES (with other children) had a break at the same place. The mine is very popular because of its hardness, especially among young and probably more difficult to break. This suggests to me that it is already broken in the pen and the Spitzer has the piece just exposed.

It did not last even a week since I got a new device that works perfectly. And the overarching countries in shipping! :)
