I have to that one and the regular all in one measuing cups that you slide the handle to the desired measurement and the same with the spoons. I love mine!
I mostly use the displacement cup for butter, sour cream, wet solids like that. My other are used for dry solids and I use my spoons for everything. It's easier than trying to find the right ones that have 5 or 6 different cups or spoons.
These are the new ones from The Pampered Chef. They are wonderful.
