Product review (4 stars): Nice unit
This unit is very nice for the money, but the installation instructions are terrible.  Also, I would "strongly" suggest to not use the sheetrock anchors with bolts and count on those to keep the hood in place.  I sent an email to Akdy and asked them point blank if that would hold the hood and got no response.  I anchored mine in place with lag bolts into the ceiling joists and it isn't going anywhere.
I did get some help from another buyer so I appreciate that.
