Regarding the M5, I think its excellent. With the M5, you can move around objects with your mind, you can cut a deck of cards without touching it, vanish objects, etc.
However, I would not recommended it for beginner magicians. Along with the M5, there has to be presentation and a performance. Additionally, it helps if one knows how to manage spectators. If one has the necessary prerequisites, then the M5, in my opinion, is fantastic.
I cannot comment on Electric Touch, but you can check out a review here --
