I read a lot of the reviews prior to purchasing the 10 piece set, I agree with needing better insulated handles, but I don't know how they would accomplish this and have it oven safe up to 500 degrees.
I don't know if they changed the cookware since some of these reviews were written.  I cook egg whites ever morning, with and without butter, I have never had them sick and they cook beautifully.
I cooked candy yesterday in the 2.5 sauce pan, it worked beautifully, kept a steady heat.  Because of the shape of the pan it was easy to get all the ingredients incorporated.
I wished I had gotten the larger set I really need the larger pots and pans for my family of 4, live and learn.....
