I'm with Joe on this one. I'm not the cook, but I'm the guy that cleans the hood. I'm also the guy who, in spite of a degree in physics, fell for the line spun by VentaHood. I should be ashamed. Ours is old -- about 15 years -- and it only has one speed (the right speed for getting the grease out of the air!!). It's noisy. Neither the cook nor I like it.
