If the eraser is not working ...

Unfortunately, Amazon takes care of the link out ...

Troubleshooting advised there to remove the contact rubber on the Radiergummiseite. Among them is a Phillips head screw which should be loosened slightly. Hab troubleshooting described and tried my eraser works now! Although annoying, because it really matters to a quarter turn of the screw, and each time the cap has to be removed, but better than to return and hope that the new works ...

The manual is of course at your own risk - but can break this really nothing!

Since he still had outs anyway, I had again contact with the support, who advised me to swap the cap to the enclosed spare. It sounds not very logical, but help! The support answered the rest within five minutes on my mail inquiry !!

Due to the fact that it does not work "out of the box" really two star deduction!
