These cups are very nice indeed, of course they are not of the same quality as the Penguin cups but
for 20$ you get a lot of good stuff. Not to mention that I was able to find two other balls that are
exactly like the one that came with my set so now I have 3 balls of different colors to use as big
loads.
So now I have all the tools to practice and perform great routines. Don't worry
about reflections in the aluminum, if you handle them right no one will ever pick it up.
I
might get a set of high quality cups someday, but I don't see the necessity at this point. For the
moment I have four great routines down including the one shown in the demo for the copper Penguin
Cups and people just love it!!!
One more thing though... Practice!!! ;)
