I simply purchased this product after very little review from an east coast boat building group. I was wanting an orbital sander and a complimentary vacuume to keep dust levels at a minimum. Sanding epoxy away from a wooden kayak was a chore prior to this purchase. I coupled a fesstool 150 with this vac. And, i do not regret the marriage! Myne either. Although a small bit of sanding dust will enter my nostril area, i think this a fair trade off with the ability to see what the surface is like as i pass the orbital about. I am happy with this unit and the noise is completely at a low decibal. The purchase was intuitive with little concern for mass review and research. That's how i purchase anyway. This seems to work for me. Thanks Fein! And thanks to Fesstool for a sweet orbital sander.
