Product review (2 stars): Kucht Pro-Style Hood
Bought this hood based on specs, no seriously negative reviews, really not much reviews at all.  Came well boxed, the directions were written as if from a non-English speaking version.  Other odd thing was the first 2 pages of the manual were missing.  Thus the brand of the product, any contact information was missing.  To me, looked like the Kucht is a rebrand (possibly of Thor Kitchen), part of original manual removed to hide this.
The mechanical issue I noticed once installed, was one of the blower canister (the spinning thing with all the vanes) was not balanced, actually not round.  So the fan turns on, big vibration, metal interference on part of the rotation.  Serious issue.  Limited testing, so can't say much at this time, but other than the function, other things seem ok.  I feel that despite the poor directions for install/usage, I could figure it out, but the malfunctioning fan is major.  Will try to contact company, get another fan canister, then update review.
