Product review (4 stars): Happy Camper with fan.
Easy to install, looks nice and seems to work. Has 3 speeds of fan low, + & ++ gets louder as the fan speeds up. No rattles  just squirrel cage fan  noise.(Installed at 30.5) rated at 30" minimum for gas above gas cook-top . Draws smoke very well even at low speed.  I like having the buttons vs led display. Cleaning is easy with a stainless steel/mineral oils  combo we got with our new gas cook-top. Excellent Amazon customer service and also easy to contact Ancona for info. I'd give it 5 stars but the term " I love it " not appropriate for a Fan??
