I bought function 9 and I must say this is the trick I perform most people are amazed and it's not
too difficult nothing. A little mirror practice won't fix and it looks phenomenal as for downsides
u have to make the gimmick but u probably have the items around ur house if not they can be bought
for under 5$ and u have to make it well but it's not toodifficult all in all 4 out of 5 and a
definite buy if u ask me
