Product review (3 stars): Didn't expect much, got what I expected..
I had to replace a very old range hood (one that had the top vent about 2 inches off center), and I wasn't looking to replace it with the of the uber hoods, so this worked fine.  I had to manhandle it into the spot (remember that 2 inches off center thing? Sucked), but it works fine.  The fan is a little loud, and it's definitely cheaper made than my last one - plastic fan, only one poorly fitting screen, but it's there now, so I won't have to think about it again for a while (I hope).
