Rating : - Fantastic value - excellent product!
I use these Pyrex round storage containers constantly. There are probably more than a dozen in my refrigerator right now. The 2-cup and the 4-cup sizes get the biggest workout in our family of four. We use the 4-cup size to microwave nearly all of our frozen or canned vegetables. It holds plenty for a generous dinner portion for us all. Then, the 2-cup holds the leftovers! The 1-cup size is great for storing small portions of veggies or egg whites, chopped nuts, etc. for baking. A large portion of homemade soup, stew, or spaghetti sauce fits perfectly in the 7-cup size.

I absolutely love the flat bottoms on these pieces. They stack up in the fridge without a problem and they NEVER tip over.

I own many rectangular and round Pyrex storage containers and I truly love them. When empty, they all nest nicely in my cupboard. I put each bowl on top of its lid, then place the bowl-plus-lid inside a larger size.

It's great to be able to look in my refrigerator and see at a glance what I have in there. The glass bowls never stain, so they always look great.

The Pyrex bowl just keeps on going - I've had all of mine at least 12 years. The lids, however, are another story. Washing them in the dishwasher and putting them in the microwave cause them to crack too quickly. Thankfully, replacements can be purchased online at World Kitchen. I wish Amazon would offer the replacement lids as well, though.

If I could choose only one type of storage container for my kitchen, these Pyrex glass containers with plastic lids would be my choice.
