Product review (4 stars): Not installation-frendly
I used Kobe Range Hood for six year in my old house  and never had any problem  That's why I just got this one for my new home recently. It's horrible. 1) It doesn't come with screws; 2) it's really just for horizontal vent; I have rear vent, so I have to cut a hole on rear in order to vent out; 3) even I haven't used it yet,  i can tell it will be difficult to clean; if you want to clean the fan, you need to remove the entire cover. 4) not comes with paper instructions(should we expect handyman bring a computer to play the DVD?) I give one star for now, and will update the performance.
update  :
using about 3 months, 1. Clean, no much grease stick on panel, 2. Powerful, speed 3 works very well, so I raise 4 star from 1.
