I'm really skeptical about online product descriptions and marketing hype, after purchasing, receiving and using this dual action polisher, I'm a believer. Its significantly more powerful, smoother, quieter, and comfortable than my DAS6. The build quality is top notch, ergonomics perfect and very well balanced/weighted. I don't use my Flex 3401 anymore since receiving this, its that good. It certainly has alot of power as evident by it not stalling easily, a feat considering its a free float DA. This polisher is also quieter than my Rupes. I would certainly give it 6 stars if I could. Its such a pleasure to use I'm thinking of getting a second one. Well done UF, you have a winner here.
