Product review (3 stars): Wipe it down every time you fry!
The fan works okay, but doesn't pull the aerosolized grease into the filter efficiently enough. The stainless is prone grease marks that can be difficult to remove if you don't do it right away. I have to wipe it down every time I fry something. This means I have to pull out our step ladder and wipe it from top to bottom. So now I'm investing in splatter screens for all my pans.
