I wanted to like this set. It looks pretty good from a distance, like Paul-Fox-style, or perhaps
Bertram-style, cups. Up close, the seams are painfully visible.
Usability is a nightmare.
The top indent is so deep and there is so much attic space that you can hear hidden balls rolling in
the nested or stacked cups. The tacky surface of the rubber balls makes them great to manipulate,
but cause them to hang up A LOT. The Up-the-Ladder Move, the Tipoff Move, and doing the inertia move
to a cup going onto a stack or loading a cup going onto a stack are difficult or nearly impossible.
You could get a set of crocheted cork balls, but then you might as well try some of the Uday cups
available here. I think most will find the additional weight of even aluminum cups to improve
handling (and I like light cups, but these are a bit TOO light, being plastic).
Overall,
the cheapest metal cups you could find will probably serve you better if you're a beginner and/or on
a budget.
