Query: Not the Calphalon I know

I am very disappointed with this product and the other Calphalon pieces I bought with it. I've had three Calphalon pieces for 2 years now and love them for how they keep an even temperature and cleanup with only a sponge. The Calphalon I purchased here is entirely different. It's very hard to keep an even temp. when cooking and the worst of all is that foods I cook in them stick and take a lot of work to clean. I've tried cleaning them immediately after cooking (instead of eating what I cooked), I've tried soaking them to no avail. I still have to spend a good amount of time scrubbing them with a soft sponge. The feel of the cookware is different than my other Calphalon as well. It's thinner somehow and feels "cheaper". I've learned my lesson, I won't buy this type of cookware online anymore, no matter how good of a deal it appears to be.
