Product review (5 stars): Good quality
Nice fan for the money. Used for home brewing exhaust to keep my wife happy. Very quiet. Included 6" expandable duct does not fit common sheet metal couplers and elbows so be prepared if those are part of your hookup. Update 3/3/18: I noticed that in many cases the fan would either shut off or change speeds after operating for 20-30 minutes after condensation builds up on inside of hood. Turns out condensate would accumulate between touchscreen and electronics. I placed a piece of HVAC duct tape above electronics to divert condensate and i works fine so far.
