Product review (4 stars): Plan ahead if you don't have a flat surface to attach this to
This is a great quick fix if you're in a house where you want some sort of over-range light and extremely mild ventilation-esque behavior.  It really is easy to install - kill power at the breaker, match colors of wires and you're good.  HOWEVER!!!  If you do not have a flat surface to affix this to (ours had wood around the side, but about 1-2 inches of recess until you hit the plywood "floor" of the cabinet above the range), you will need some wood shims you'll need to install first, or really wing it with the screws and the angles at which you insert said screws through any hole you can find that might remotely be near wood.  This thing is really lightweight, so you don't have to worry about it falling on you unless you like to lean on your vent hoods or hang things from them.
