Love the bowls.  I had the 4qt one and wanted another for my breadmaking.  When I saw the set for just a few dollars more than the individual bowl, I decided to purchase the set, as Pyrex can be put in the oven or microwave and they all have lids which is important to me.  There is flaw in the 4qt bowl I received but I don’t think it will affect the performance of the bowl.  Overall I am happy with the set.
