If you are considering an RO buffer/polisher, but you are on the fence about which one to buy, I want to share my experience.
I have a Griots Garage 6 in RO buffer, that has seen 4 years of use. The last time I used it, I noticed a small amount of oil on the gearbox (the part the above the pad holder that translates the spinning motor shaft into a random orbital pattern). It was not much, but I thought I would send an email to customer service and see if I should perform some sort of maintenance to replace the lost oil, and to seal the leak. I received an email from them the next day, and they requested my customer number and purchase date. They also said that as soon as they located my original purchase documents, they would send me a UPS return label, and ship me a new unit as soon as they received my old one! There were no questions about misuse or abuse. They never asked if I had dropped the unit, in fact, there were no questions at all. I was really surprised. I assumed that they would send a factory refurb unit, so I asked about that. But no, it is a brand new, 2011 model, NIB. You can make various arguments about the quality of their polishes, etc, but you can not argue with that kind of customer service. To be honest, I do not see any major differences in the performance of other companies products in the $200 price range, so this kind of service should be enough to tip the scales in favor of a Griots RO buffer. I really doubt that any of the other companies have this sort of return policy for their products once the warranty expires.
