I think the product is performing as advertised, although the other day I poached 4 eggs and one turned out badly undercooked. More water needed? The issue is learning how to use it. I have much better luck with good cuts of meat and fish, which I can bring to an even temperature from top to bottom. I have had less luck with roasts of lesser cuts, as the temps used do not render the fat in the cuts. I will keep playing with it.
