Very poor. The chop cup is heavier and bigger than the other 2 cups. It also stays in better
condition than the other two, which in performance looks terrible because the audience sees two
dirty cups and 1 clean??
Also the three cups do not stack well at all. They wobble and are not
aligned. One last thing, being a bit picky on this one but the instructions included, were written
for aluminum cups, which shows that the producers are cheap. This is all Uday's fault, not
penguin's, I think penguin should contact Uday and discuss it. I got a refund for them and now have
the penguin cups which are excellent but I had to use my money to send them back. I would have been
handier if they just told me to keep them, because I presume they won't even be selling them. Do not
buy
