Was looking for a replacement rangehood for my kitchen as we do lots of Asian cooking (oily, smoky etc), based on research people has been recommending brands such as robam, fotile, pacific.
This particular brand (Fotile) has been viewed as quite decent one also have checked with friends who already used them for a few years.
This particular unit sold on their website for $2099.99 ( link ) including delivery hence with costco deal it's a saving of $600 (not sure why costco wrote $300 savings)
Installation from Fotile will be around $500 which basically cover the exhaust to go through the roof.
I would say do your research and decide accordingly as I know there are other known brand which might perform better such as schweigen or Qasair but they do cost more.
got one at home, recommended for asian cooking I was told, the touchless on and off keeps the front glass clean most of the time. I diy installed, replacing an existing rangehood which already had a flute going out the side of the house. Pretty easy to clean.
