I am not a magician just enterain grandkids. With this in mind Sandwich change was fun to do, relatively easy and worked well. I would recommend without resevation.

Ok so these guys finally start putting out ready to go out the box gimmicks. However I promise you will be disappointed with this one. It is very difficult to set up on the spur of the moment. You will get busted even if your good with card magic. The video is of course well made and you will learn to make your own gimmick. And I will be remaking mine.

the gimmick is hard to make and it does not work smoothly all the time and you will never see any magician using this kind of gimmick it louses it speed pretty fast and in the video he says cap the marker and the camera cuts away from him cause he will look like he is doing something tricky and it will not look like magic. just watch the video where he says cap the pen.

This was the first SansMinds effect I purchased,... It's ok. Not really hard to work, it WILL take practice as the best tricks do. YET, I found that the gaff will not act as quickly as shown on trailer or even in the instructions. So, I took it apart and redid it. You may need a little extra thumb work to secure the gaff when the card has changed in the spectators hand. Yet again, timing is the KEY. AND I believe the Magi out there will get it down.
I wanted to give this 5 stars BECAUSE it is a very good trick,... I believe it allows the Magi to work on their presentation,... You will want to watch angles abit, lighting abit,.. yet they cover it is the instructional video.
I was happy with the overall product, DVD instructions and info on how to construct your very own gaff. I like it and when doing street magic or table hopping I will use it.
Though I am working trying it with business cards,... Hmmm could be interesting.
