Very well made! The largest one is a bit heavy, but that's to be expected given it's size. We use the two smaller ones more often, as it's usually just the two of us, so usually not large meals being cooked. The larger one gets used mostly for making pancakes! Very good quality, just as expected from Pyrex. Measurements are clearly marked on the sides in red. I did learn from the 2 plastic versions we have to not put them in the dishwasher with strong dishwasher detergent - that really took the red color out - not sure w/r to these glass versions, but I'm not taking any chances! I only see two ways this set could be improved - one is to ensure the red measurements can't fade in the dishwasher (which might not be needed, I'm just don't know that), and the other is to include lids... Otherwise, pretty darn perfect. Very highly recommend.
