I got this a couple of weeks ago and you a right that it doesn't take long to learn it.
The only person I've tried it on so far is my girlfriend, and unfortunatly she always wants to examine everything!!

She just doensn't trust me. I can see though that when performing to the public it would be easy enough just to put the ropes in your pocket and carry on with a different trick.
However, I don't generaly like to work with things that aren't examinable (just in case), and it struck me in bed last night (strange) that the trick could possably done with normal ropes. Haven't tried yet though. Will let you know what happens.
