Review (4/5): Loved it until there was a short in the power where the cord connects into the unit.
Update: received a replacement dust control fan today out of the blue. Very impressed that the company is standing behind their product. A little louder than I wanted but when you are using the efile you don't notice it. Noticed a huge difference with dust since I started using. Then I set in on its side while doing chemical services and it has really helped with the fumes! But the last week it has had a play in the power where the cord hooks into the unit. Have to shake the cord a little where it hooks into the fan.
