I finally got to use my Ceros sander for the first time ( after selling my house, building a new pole barn and moving ). I had bought it at the end of March just before I retired because I knew I would have a lot of sanding building my kitchen cabinets. I had to build a new workshop (barely functional at this point with limited electricity) and building a new house. This sander is by far several steps above any finish sander I have ever used, green, blue, orange and red ones. It should be at $500. I have no regrets buying it. Under 2 lbs. I used it for about 5 hours yesterday with no fatigue and my hand was not still shaking when I quit. I used it with the Abranet sanding discs and there is virtually no visible dust. I bought this mainly for the dust control with the Abranet discs because with my new shop I am upgrading all of the dust control. Added benefits are the ease of sanding and low noise that I did not anticipate to the extent this sander provides. I really like the off on paddle control. The Abranet discs provide some of the benefit, but the sander itself provides much more. Glad I had the nerve to spend this amount of money on this sander and would do it again. As far as disadvantages it probably will not trigger a vac, but not an issue for me.
