Product review (2 stars): The stainless steel cover of the range hood is dirty upon unpack
The unit I received seems not brand new. The stainless steel cover of the range hood is dirty upon unpack. and seems there was a plastic layer on it before. Upon unpack,  I wish I can return the unit, but too bad I've already remove my old range hood, and we can not live without range hood for another couple of days...
The size of the outlet is not exactly 8 inch, it's actually outlet diamention is ~7.5inch. The pipe I purchased from Home Depot won't fit.
Not easy to install, no flexibility for the mount position, I have to figure a different way other than what's instruction descriped to install it.

The performance is not bad though, I have a very short pipe.
