I bought these with a 2 for 1 pricing. They have a beautiful yellow color. The ONLY thing I would change is how they stack. You place the lid of the smaller sized bowl inside the next largest bowl, until you get to the top bowl and it just lays on top. Nothing secure in that process. 

Pros: Color, easy washing, dishwasher, refrigerator and they say microwave safe. I have only tried a few things in them in the microwave. I would never put tomato-based items in them.
Cons: They will break. Had a lid break when it dropped on my ceramic tile. Do not like that the  lids do not fit in some way to keep all of them clean together.
