The cups and balls were what I was looking for: metal chop cup with 2 others. I've performed with
them numerous times and they work fine.
What's not perfect? They aren't all the same. The chop
cup is taller than the other 2, has lost its shine much faster than the other 2, but is tougher and
undented, whereas the other 2, which are still shiny, have small dents (which don't affect the
performance). Maybe I have to spend $200 to avoid the problems in this paragraph, but I'm happy
with the price and no one has complained about what I just mentioned.
