First you should know that lighting is everything for this effect. It is VERY easy to control but it does take some time and playing with it to make it look natural. The B.U.G. device (Butterfly Utility Gimmick) is straight forward and easy to slip on and off. (those with darker skin be aware that even on my skin it looks very pale) Those that work with a thumbtip should have no problems with this. There are some good ideas and some bad ideas (you can decide yourself) on the DVD.
My only real negative comment is from the DVD when you are on the teach the trick segment, sometimes what he wants you to see is off frame so be mindful of that fact.
I think its a winner with what I'm doing and an excellent follow up with a floating butterfly routine I use with a thread bullet I have.
