I'm torn between being rash and opting for a slanted 'feature' extractor or being sensible and boring (my son's opinion) and getting a built in one. I really like www.besthoods.co.uk/product-catalogue/wall-mounted-hoods/surf/
But are they practical? It seems to have decent airflow. Do they get very mucky? Do they actually work?! Does the steam just drip down slated hoods?
