I had this product professionally installed, very poor suction - our fire alarm keeps going off making me wonder if it is actually sucking anything.  When I'm cooking, I can watch the fumes bypass the unit.  There is some suction but it just isn't very strong at all. Also worth noting the LED clock is super bright with no way to dim it, so I guess it will function as a night light as well.
