Product review (4 stars): I hated installing it
It gets the kitchen odors out of the house! Other than that, there isn't much to say. I hated installing it. Very flimsy metal and sharp corners for the flange part. Cutting into the shingles of your once perfectly water tight roof is always a big pucker moment! Liberal use of a good roofing sealant and a few nails later and the job is thankfully over. The bird screen is just some metal mesh that is sort of wedged up in there. You would think they could devise some better way of mounting the mesh than "eh, just jam it up in there"... But it keeps the birds out. And if you build homes for a living, please do the world a favor and just add an outdoor vent like this for the range hood!!! Just do it! even if it's one of those silly microwave above the range deals, just run the duct and this vent anyway! even if it's a wall vent. Recirculating vents do not work and no one wants their house full of cooking odors. Seriously. It should just be code.
