Like most sets, a ring is included to keep them together when nested. Traditionally, the ring is troublesome because removing a cup also requires the removal of cups that come before it. This problem has been solved by opening the handles’ holes on one side, allowing you to pull a cup off of the ring via the opening and then simply clip it back in place. Additionally, the rubber on the handle is set back a good bit from the cup, allowing for easy leveling with a knife.
The build quality is excellent. The cup and handle are fashioned from a single piece of surprisingly thick steel, eliminating the weakness of a weld point. Each cup’s measurement value is permanently inlaid into the rubber handle, such that no amount of scrubbing will take it off.
A similar plastic set is also produced under the Good Grips moniker. It features the same open-holed handles and inlaid measurement values and is slightly cheaper than the steel set, but it takes up more room by including unnecessary ⅔ and ¾ cups.
Regardless of whether you opt for steel or plastic, these cups will probably be the last set you ever buy. – Cody Raspen
