Product review (3 stars): Beware The Air Space Requirement
I got this from amazon warehouse deals and it turned out not to work at all.  I returned the unit with no problem and no cost to me.  So that part is great.  However, buyers please be aware that the unit requires 2-3 inches of air behind it when installed under a counter.  My counter is just 24" so it would not have worked anyway.  If your counter is 27 inches or more in depth, then you should be OK.
