Query: Do NOT waste your money!

Do NOT waste your money on Calphalon Stainless cookware!I bought a set and couldn't wait to give it away! It spits and sputters steam that condenses under the glass lid, no matter what you're cooking, no matter what temperature you try. I was horrified to pick up a consumer reports and found that they had rated this cookware so highly.I believe that Calphalon is aware of this and should rectify, replace or refund money on this cookware. I contacted them and they never responded.Do a search on Google under "calphalon spits" and see what you find. I always had a huge mess on my glass stove top no matter what.
