Not many people would have a performing venue that would allow you to perform this, but if you have
a place you can do it then it's a great effect!
It's also really fun to do!
It
does take a while to get used to operating the drone, but the creators were available by email and
always happy to help. Thankfully, operating a drone indoors is far easier than outdoors so when
you perform this it's quite easy to keep control.
Thanks to my aviation background
(pilot, drone pilot, glider pilot, skydiving) I was concerned about safety, but the directions
clearly explain how to do the trick safely, if you follow the instructions this trick is completely
safe. Of course you can hurt people with anything, but after following the instructions and
performing it several time I believe it's as safe as most card tricks
