I'm a consultant, so I may be biased. Having said that, I do love my cookware. I use it every day and I swear I don't know how I ever lived with crappy pots and pans for the first 10 years of my marriage. I use the non-stick line. The stainless is made really well too, but I'm just a nonstick kind of girl. First of all, you can put a package of frozen meat on the cookware at room temperature and that sucker is defrosted in absolutely no time (it's all in how well the material conducts heat). Also, I often sear meats/chicken/fish at a very high temp and then finish it in the oven. Going from stove top to oven changed the way I cooked. The large 12 inch skillet with the 2nd handle is amazing. I cook almost everything in that pan. Made roasted chicken with veggies & potatoes last night and then I made a delicious pan gravy after it came out of the oven.
Are they expensive? Yes. Are they worth it? Yes, IMHO. I have many people who will Host a show just to get a set at half price or free (that's always my suggestion, although people buy them outright too). Lifetime warantee so no worries there. They're also nonstick on the inside AND outside, so they clean up beautifully. The ARE NOT coated with the nonstick coating you see on cheaper stuff. THEY WILL NEVER FLAKE nonstick coating into your food - ever. Yes, they can scratch, but they're never flake. They are a true workhorse in the kitchen.
Getting off my soapbox now. FYI, to get them for half price as a Host, you'd need $300 in guest orders. With that, you could get the 5 & 7 piece sets combined as a half price item and it would cost you $395. If you just wanted the 5 piece set, half price would be $157. The 7 piece set at half price would be $237. There are also open stock pieces too.
If you'd like to see my website, message me and I'll send you the link (I don't want to show it here since I think that might be against the rules). Good luck with whatever you decide.
