Well I was thinking about adding a Rotex 125 to my arsenal to use in my sculpted Maloof inspired dining set I am building. The 6 inch Rotex is too big for many areas and the RO90 is too small, so I wanted the 125mm size to follow my RAS. After trying it out and the new ETS EC125, I was blown away by the power and feel of the new ETS and so I came home with one to try. I figured I could take advantage of the 30 days and if it does not work, I can swap it for the Rotex 125 (which I also liked). I think that I am going to be happy with the ETS and the brake, weight, ergonomics and power were amazing. Festool seems to have gotten things right with this sander.
