I just thought I'd share a recent experience with Calphalon that was very positive. I often buy Calphalon Seconds at a local Outlet mall. For years I abused them and tossed them in the recycle bin as they were pretty darn cheap. Mostly I had trouble with the anodized finish wearing off the inside bottom of the Commercial series. A few years back I replaced an 8 QT stock pot but decided to send the old one back to see if Calphalon would cover it under warranty. Sure enough I received a new 8QT stock pot. Calphalon's warranty even applied to factory seconds! I recently sent another pot in with the same issue. Calphalon was apparently bought out by Rubbermaid and has discontinued a number of the Commercial Line anodized products. The factory rep I spoke to told me they would send me a check and I thought I'd be waiting a year to get it. Less than four weeks from returning the pot I received my refund. If you ever have a Calphalon product wear out don't make the mistake I did in the past by tossing them. Send them back to the factory. No receipt was required!
