I received the Harmonica Chop Cup (black) and tried to put it into rehearsal. Unfortunately, no
balls were included. I tried to use the balls from one, then another set that I have, but they did
not work. There was no 'staying power' with either set, though they work very well with their
original cups.
I had to buy a set of balls - one 'adjustable' and a matching one from
Rings-N-Things, and, as expected, I had to make major adjustments in order to tune the effect.
Having to make the additional purchase was significant and increased the cost of the effect much
more than should have.
The round metal box that the cup comes in is nice, but very thin and
I doubt if it will stand up to a working magician's needs without soon being too bent to use.
The cup itself is a good size, though the definition of that term will vary from performer to
performer, and the color is consistent throughout.
It collapses with a bit of manipulation,
but that is to be expected.
Overall, I expect to use this cup during walk-around and
table-hopping. That makes it a usable prop with an advantages for being a bit unusual and for being
collapsible.
If it had included a set of balls, as all of my other chop cups have, my
rating would have been higher. It would have been acceptable if I could have used balls from another
set. Having to buy a set of balls in order to obtain an adjustable ball (which cost me both time and
not a little money) was a strong negative.
