Prime Shadow Spring

This is an amazing move. It does take some practice but definitely worth buying.

This is the coolest move, highly recommended.

For me it's very good and impressive move. If you know how to do card spring it's not hard to learn and it's fun to practice!

THIS BLEW MY MIND! Before and after learning the trick. Though an advanced move, I was able to do it after about a day. BUY IT NOW!

This?is?amazing. This move only took me around 45 minutes to get down and it is stellar. I can't think of a bad thing about it. By far the best $9 I ever spent on Ellusionist. You could use this move as a control of literally just a an entire routine in itself. Buy this, and it will be the best decision of your day.

This is absolutely BRILLIANT! Ben Prime has taken the card spring and refined it to a master technique like no other! If you love moves with NO gimmicks this is for you. In fact if you just love beautiful magic this is for you. This is a must have move/trick/technique every true magician should learn. I am absolutely blown away by the creative thinking and beautiful moves of Ben Prime! THIS IS A MUST BUY!!!!

This sleight is brilliant.
Until you get really good at it, it is a bit angle sensitive. For example if you aren't good at concealing the movement you can simply rotate such that the cards are facing the spectator and the move is invisible.
I have only had this move for about a week but I already find it working wonders on everyone I show it to, including fellow magicians.
A must get!

This move is incredible and Ben's use for a chosen card at any number with this sleight is one of my favourites to perform.

It fools laymen, and it ruins magicians. I haven't seen a sleight this new and exciting since learning the clipshift in 2008.

Super awesome slight ONLY if you are ready to give this the time. The applications you see in the trailer are exactly what you get. Don't get it if you're just curious. Also, pretty sure this is on magic stream so just get that instead.

Resourceful tool to add to your arsenal! Very well explained and performed. A little angle sensitive and appears clumsy until perfected through practice. Not one of those sleights you can pull off with little passion and ease. Don't let my review discourage you though! If you really want to see this sleight through, I know you will practice lots!
