I would not recommend this trick, for two reasons. First, in my view it is fundamentally not a good trick, because the actual effect is not clear. Is it a prediction? Or are you changing the color of the cards by magic? You are showing all the cards to be one color, making predictions, then the colors of the cards change to match your prediction? It makes no sense to pretend you are able to predict the future, but then also pretend you have magic abilities to change the cards to make your predictions accurate. So ok -- it doesn't make sense but offers a quirky moment of surprise. Fine. But further, there is an element of risk here -- it is far from foolproof. It is easy to do, but you either need to rely on good audience management, or, if you let the spectator do the cutting, as suggested as an alternate method, you need to hope the spectators treat the cards extremely carefully (which many spectators don't). I'm happy to take risks for a great payoff. Here, I think the effect and payoff is mediocre, an in my opinion not worth any risk.
Bottom line: If you watch the trailer and really like the effect, then go for it. However, if you have any experience with card magic, you will understand the method immediately and will just probably make it yourself, which you can do for about $15 if you don't already have what you need at home. If you really like it but don't understand the method, then buy it, but understand that, while it is easy, you need a bit of finesse and experience to get it to go smoothly.
