We have only used the 10' pan so far, but we will be purchasing the rest of the set due to how much we like this pan.  I liked it enough to purchase a second one for our camping set.  You can feel the quality in the weight of it and see the quality in how it cooks.  It heats evenly and cleans easily.  It is worth the money as it will not have to be replaced for a very long time.  Make the investment and add this to your kitchen.  So far we have fried eggs, veggies for fajitas, browned various meats (pork and beef), and fried bacon in it.  It still looks new and unused.
