When it comes to reviews for bizarre magic and mentalism, I'm getting a little tired of the phrase "I wish he would not have released this, it's too powerful" It appears on almost all the products I've I looked at recently. It's lazy plugging. Also there is no such thing as an effect that is too powerful. Unless theirs one that like kills a certain percentage of the audience that can't handle that level of power. That effect may be too powerful.
