Query: Falls far short of the Calphalon reputation for good cookware

I own many pieces of Calphalon. This stainless steel pan is awful. I meticulously read the instructions before using this grill pan. I used it one time - nothing elaborate (simple turkey burgers) - following the cooking and cleaning instructions. It should have looked like new after one use ... but I tried and tried but couldn't get it completely clean. DON'T BUY IT.I bought this on Amazon (FireFly Buys). Firefly refused to take it back because they consider it 'used'. (How would you know it was a bad product...if you didn't use it?) I certainly have a very negative review for the seller.
