... Unfortunately, the adhesion of the disks compared to other grinding wheels is just bad. This does not keep the windows properly on the machine that is not reasonably possible to work. I had already read in the Product Reviews this. However, I had assumed when I without solving in between use the discs to the end that they hold. This is unfortunately not the case. After all my discs of 120 grit were once fallen they were also at low speed just until they dropped back more seconds. Then I'm frustrated drove to the hardware store and have brought others and completed my work. Although the were much more expensive, but have at least works. Therefore, only a tired star.
