Hey guys, new to the forum, getting back into the detailing thing after a long absence. I bought a GG6 DA after comparing the three most popular DA polishers on the market, you know what they are. I'm very disappointed in the amount of vibration I was getting from the GG6, my hands were numb and tingly after the first 15 minutes of use on setting 3. And yes I made sure my pads were centered and everything was snug and tight. Looks I'll be returning it and going with the Flex 3401.
