Product review (1 stars): Never had a range hood that cost you sleep?  This may be for you.
This fourth range hood obtained from Kobe was the first that could be mounted so that it was not a visual disaster.  Three came with obvious surface warps and irregularities that made it impossible to mount beneath a frameless cabinet without a disturbingly uneven seam.  This one came with a damaged motor mount that made a repeated, loud banging noise on low speed as the motor continuously hit and rebounded from the housing containing it.  I feared that another replacement might fix the motor and bring me another warped hood, so I took the motor and housing apart and re-shaped quite bent parts, replacing a completely missing mounting screw and nut, and adding washers so the existing machine screws would not fall through openings widened by over-torqued assembly procedures.  Additionally, I threw out Kobe's installation instructions and created my own custom assembly -- the only way a satisfactory installation can be done, in my experience.  It included detaching the hood from the motor housing, mounting the motor from inside the cabinet, not from below, adding a piece of 3/16" masonite with black-painted edge to drop the hood far enough below the cabinet to avoid scratching the hood's top with bottom-mounted cabinet pulls, buying longer stainless machine screws to attach the hood, sealing the gap between hood and motor with aluminum tape, protecting the sides and rear of the cabinet that the hood leaves exposed with more aluminum tape, and adding an internal aircraft-grade aluminum right angle brace to keep the hood from drooping at either end.  Sound like a lot to do?  It sure is.  Add to that experience that four orders/three returns and my custom work took months to have a working range hood, and you can see what I endured.  Sadly, I had purchased a cabinet with a Kobe hood in mind, and that severely limited my options when trouble arose.  If you are adventurous, you might want to have one.  Mine now works, and its slender, modern style -- what attracted me to it in the first place -- is unquestionably attractive.  But the experience I had demonstrates an absurdly poor level of quality control and a shocking lack of consideration for installation issues one is likely to encounter that its design has absolutely no accommodation for, save those a consumer is able to devise on his own.
