I use this cookware in the oven a lot, something many other brands can't sustain.  The pots and pans from two sets I own (10-piece and 7-piece compact) have replaced my casserole dishes, roasting pans and baking dishes!  I know the lids aren't really supposed to go into the oven, but I don't bake higher than 350 degrees and none of my lids have warped or discolored to this day.  They are stainless steel, after all!  Barkeeper's Friend cleans every pot and pan every time like new so far.  I never put my All-Clad in the dishwasher and never will.
