Product review (5 stars): Just Right
I bought this to replace the old non-ducted hood (from the same manufacturer) in my kitchen.  Despite the old hood being 20+ years old, this was an exact fit.  Cutting a hole through my house for the ducting was daunting, but straightforward.  Aside from that, installation was a breeze.  I am so happy to not have smoke from my meat blown back in my face!
