I have been using the Festool Dust Extractors and Festool sanders in my Wood classes for over four years now. Currently, I have 10 sanders and 5 dust extractors. My room used to be filled with airborne dust while all of my students were sanding, but no more! Dust is no longer an issue, and the sanders are the highest quality that I have ever used. I would recommend these sanders and dust extractors to everyone! Trish O., Iowa
