Product review (5 stars): The hood design could be better, but since I'm only reviewing the screens
Lasts a long time provided you put it through the dish washer every few weeks.  I cook Asian food all the time on an electric stove, high heat, lots of stir frying.  It traps alot of the oil.  The hood design could be better, but since I'm only reviewing the screens, we'll stick to their role specifically.

The last screens I had lasted 5 years.  I expect these will last until I change the hood in the next few years.

Highly recommend if you have this hood design.
