I don't like using this part of the site for "advertising" but this is really more of a testimonial than advertising. I have been in the process of refinishing the front door of our house for about 18 months. Needless to say it hasn't been at the top of my list....  Last week my wife raised its level of priority. I am not a big fan of refinishing, especially sanding. I brought home a Festool R/O sander and a Festool CT Mini Vac. I finished about 3/4 of the door by the time it got dark. I did a lot of sanding, yet I was not covered with sawdust, nor was the surrounding area and I was not deaf even though I did not wear hearing protection. The Festool combo was so potent that I actually am looking forward to finishing the project. If you have a sanding project in the near future and don't have a Festool sander of your own, let me know and I will loan you ours... and you will become a convert. It's that good.
