The gimmick is somewhat hard to fit in your hand and with that said it can be very hard to conceal
from certain angles. Not to mention it is somewhat hard to manipulate.Therefore, without enough
practice (about a week depending on the magician) I wouldn't suggest it. However, if you do have
enough time to get used to it so that you can perform it effectively, I would definitely recommend
it. It is a beautiful effect and personally, I used it to close one of my larger shows a few weeks
ago and it worked great.
