So this version like the million other versions is just 1 more method to do a t and r. The upside to this is its visual it's a piece by piece restoration. It is fairly easy to do with some practice and you are left clean. Also the card CAN be handed out for examination after your done. The only downside to this is the prep. The prep takes about 3-4 min give or take to make "1 card" for the effect. If you want to perform a bunch of these be prepared to spend some time making them up. Once you made up a few your ready to go. The only thing also to bear in mind is your angles. This is a fairly fair angle sensitive effect but people can see what your doing from the side so bear that in mind. Overall though I liked it. It's a good visual version and maybe my favorite version in terms of visuality. It terms of practicality not quite. If I were you reading this I would buy it.
