I already owned the 3 smaller bowls though without lids. I made this purchase because it was cheaper to buy the set than to buy the large bowl separately and I need the 4 quart bowl for making bread dough. I love Pyrex bowls but the caveat here is the lids do not seem to seal very well. This is not an issue for my purposes because it need not be airtight for bread dough. But if you need them to seal properly, then I would look at a different set or buy them in store.

Pros: Great price, Exactly what I needed, Nothing damaged in delivery
Cons: Lids not airtight
