Even at the original $10 price this is a good value, but for half off it's a steal!
One question
I had was can you do this standing up? Yes, you can, but you still need a surface to set the cups on
and slide them around, and it is best if that surface is near your waist height.
Trick doesn't
use any sleights, and there aren't any angle problems, but you certainly should practice it several
times to help you figure out spectator management. A grabby spectator can possibly ruin the trick.
For that reason I feel this is best as a one on one presentation. I definitely would not do it for a
group of 3 or more guys unless you already know they are chill.
