Product review (2 stars): It looks sorta cheesy in real life like a nike swoosh over your oven
Really don't know how to trust most of the reviews on here but bottom line is if you live in the US or Canada, you should pass on this unit.  The main issue is the vent flap as well as duct tube are made of plastic which is not code compliant in both countries.  Most of these AKDY units are low end Chinese models.  Mine came with some blemishes but other issues i had was the mounting holes in this unit are not lined correctly due to the asymmetrical nature of the arc.  It looks sorta cheesy in real life like a nike swoosh over your oven.  This is a very techy looking unit but i returned mine due to not being code compliant.

At the minimum look for a unit with a steel vent flap which most of these AKDYs don't have..
