This is an excellent utility device; it works beautifully. The engineering and design of this
product are indeed superb. The issue I have is not the quality of the product; it is first rate.
My issue is what Sansminds is trying to communicate via its trailer; that you can simply put this in
a spectator's hand and be able to vanish AND retrieve the ring. This is not possible. Also, if you
decide to place the ring box in the spectator's hands, you will need to use those spectator
management skills to avoid issues with the spectator knowing where the ring is. I mentioned that
this could help and that a switch is not needed in the comment section. After further testing this
in practice and in several performances, the reviewer is right in terms of needing to switch the box
if you want to avoid having issues with a spectator ruining the illusion. In terms of ideas, I
would strongly consider other ring to impossible location plots versus what is taught in this
project. For those interested in using this to isolate a spectator's ring and make it vanish under
the toughest conditions, you will not be disappointed.
