I recently just bought a UDM for doing some light polishing and for using
AIO's with. I have only used a makita rotary. I found that while polsihing with the UDM the vibration is just horrible. Is this normal. Also it is bearable below speed 4 but anything after that my whole arms just vibrate and at speed 6 it feels like after a day of polishing I would have none some seriouse harm to mhyself. Will E-Shine refund me my purchus?
