I don't usually buy things off infomercials, but I have to say I am loving this product.  What sold me is the claim that it will cook a roast from the freezer in about and hour and a half.  I was skeptical, but it was fantastic - nice and juicy, cooked all the way through but not overdone.  Everything I've tried in it has come out as good as, if not better than my oven.  And it's so much easier and quicker.  The only down side is that it does take up a lot of counter space.
