I love these bowl and use them all the time. They fit inside another set of stainless steel bowls I have that are rimless, and when I'm on a cooking spree I use all the bowls and the ceramic bowls I have, as well. They are sturdy, easy to clean, and the rim helps when I'm turning the bowl while hand mixing or using an electric mixer. They still look brand new, and I've had them quite a while now.
