Product review (3 stars): Poor installation/User Manual
This is the most disappointed that I've ever been with an Amazon product.  The instructions were written by someone with very little working of the English language (US English anyway).  None of the parts are labeled, although there are crude diagrams in the instructions.  There are 2 sets of some parts because the hood is adjustable to the ceiling; but they don't clearly mark which ones to use in which sequence.  I wound up putting most parts on at least twice before I got them right.  I ordered the optional charcoal filters for a ventless installation.  The hood instructions had nothing for ventless installation, and the filters came with no instructions at all.

The product does look good once you work thru the installation, it is nosier than expected (other reviewers said this).  It's a shame that this company will not invest in a technical writer.

Examples in Manual:
 - Title: "Cooker Hood"
 - Fix the A and B on the Blower Box assembly, show as the picture.  (In other words, study the picture closely and figure it out yourself.
 - As per the screw positions on the Upper support frame, drill 4 holes, then fill the Expanding Rubber into the holes.  Aiming the holes on the ceiling, fix the ceiling cover with the expanding screws tightly and make sure it is firm.  (this is the complete instructions for mounting the plate to the ceiling; the hood comes with plastic molly to mount it to a sheetrock ceiling - 'expanding rubber' is the plastic molly).
