The DVD is not so bad as written. The setting of the Ring/Rubberband is the hard Part, but with a
little bit of Misdirection it can be practise.
I think the most Magicians are getting little bit
lazy of practising in the last years ;-)
Fazit: Not easy to do, but after a Time of practising a
nice and strong (couse of the borrowed Ring) Routine that you can combine with other Ring routines
(Interlace).
