Query: Not the quality I expected.

I've had my set for about seven months now. I have pitting in one of my pans which leads me to believe they are not the top quality metal they claim to be. I have a ten year old set of wolfgang puck stainless steel that does not tarnish with every single use like this set does. I literally have to use barkeepers friend on them between each use to prevent sticking. I do not have to do this with my Puck set. I regret purchasing a different more expensive brand from the one that has treated me so well.
