Product review (5 stars): Very good for the price
Very good for the price.  The thickness and quality of the stainless steel was the same as major brand names that I have used.  The main vent section has slots on the back which slip onto a metal wall mounted bracket.  That was a nice touch that made it easy to get the vent mounted level.

My 2 areas of disappointment were:
1. Charcoal filters are just thin sheets on the back side of the metal mesh grates,which is before the blower motor.  Other brands have charcoal canisters like from an air respirator that mount at the top of the chimney part - which is a more thorough re-circulation filter.

2.  The lower section of the chimney stack only has mounting hole slots that face the wall.  Other brands that I have used have mounting holes on the side so they are accessible, and can be installed in sections.  The only way that I could see to use the lower chimney section mounting holes would be to mount it to the main vent section before mounting it on the wall, then slipping the whole thing with the chimney onto the wall bracket.
