Hello, I have just purchased a Proxxon 28610 - Universal Holder. IF you don't know the Proxxon 28610 is used with a Proxxon 38481 - Professional Rotary tool.
I was schocked to find out that the holder part that holds the Proxxon IBE grinder is not solid, it wobbles like crazy. I removed the ball from the stand and it seems it's not made up to the promised quality, infact how the hell do they make em ???
