Product review (1 stars): Really bad design. A bit noisy
See those little slots on the front of the hood in the photo?  If you are planning on venting it outside, there is a baffle that you unscrew and then rotate it around , and slide it back in so that it blocks those exhaust slots from the inside of the hood and the air is exhausted outside.  But it is so badly designed and there is so much wiggle room, that tons of greasy, stinky air is able to go around the blocking baffle and comes right back into the kitchen.  I tried to to block off the open areas the with some foam, but it still leaks a ton of air.  Really bad design.  A bit noisy, no lights included.  But I do like that it takes a standard GU10 bulb and I was able  put in LEDs.  (But the high/low doesn't work, no big deal.)  Overall, since it is an exhaust hood, it sucks.  I didn't get it from Amazon, and I'd return it if it wasn't such a hassle to install.
