Product review (4 stars): Good fit and good buy!
Installed easily (although I could have used a pair of spare hands), exactly fit the existing 40 year old duct, runs and lights smoothly. Do be careful with fan screen, though. It's so light that when installing, it easily rubs up against fan and makes quite a racket. It's eliminated with just a quick tweak. It runs a little noisy, but as I told my wife, "That means it's pulling out smells and heat that much faster!". I don't know if she bought it.  It's a great buy for the price. If your stove is black and stainless, why waste another $50 for the identical unit with a stainless finish. The black is very handsome and matches our new gas stove vvery well.
