Product review (4 stars): Sure, why not.
It's a good, clean solution to the bulky, rolled cheap looking vent hoods.  It tucks right up inside the custom cabinet hood and will supposedly protect the cabinets from the 'ick' of cooking debris.  I'd recommend buying it.  If you don't, there's a lot of wood that is going to be exposed to the 'ick' because you don't realize how small the power pack really is.
