I compared the Calphalon and All-Clad products to this one. The main differences are sturdier handles and slightly thicker metal on the high-end brands. I have used this product for some time and it works great. I actually bought the All-Clad but returned it when I found this one. It has a larger cooking surface area than the others. Greater surface area was my main reason for purchasing a double burner griddle. It heats evenly and is great for cooking pancakes, french toast, sausage, bacon, eggs....and more. It has a lifetime warranty and can go in the oven up to 450 F. Highly recommended!
