Review (4/5): works great...update on product 4/7/19
this products works great for its intended use, although a bit loud when turned on, but it's better than dust flying everywhere!
Update: 4/7/19. NOTE!! be careful with the free edge of the metal grate. I sliced a piece off my finger pretty bad, while brushing off excess dust off top. I put surgical tape over the free edge to avoid doing it again.
