Product review (4 stars): quiet
very quiet. good looking.

but the stainless steel is too thin.

and one more problem is the nob, to turn on the light, you must turn the right nob.
to turn on the ventilation, you must turn on the switch(on off switch).  there are two operations. you must remember  clock wise to run light, and press to turn ventilation. I make mistakes most time. I will change the connection inside to use only one switch.
