Query: Excellent value

This is *not* the highest quality that Calphalon makes, but I have never seen better, heavier bakeware. The value is fantastic, comes out to $5 per piece. You can't buy cheap bakeware for $5. The warranty is 10 years, but I see this lasting a lifetime. I would recommend this to anyone from the casual baker to the near-professional baker.
