Sixth Sense 2.5 is probably one of the top 3 things I have bought in the past few years.
It
is extraordinarily sensitive, very small, just a delight to work with!
Many pros are using
this daily - it truly is the standard by which others will be judged.
The heads/tails
feature is nice and works quite well.
I use a Kreis half along with my neo ring - and
both allow you to avoid ever touching the spectator's hand at all.
The directions and DVD
included are excellent. Great packaging too.
Highest recommendation - you could start a
religion with this thing!
