His technique is good, but you should be warned that if you are expecting a new gimmick, you will be
dissapointed. This is a technique used with an existing gimmick that you probably already have.
While I won't reveal the gimmick, I really think the seller should have revealed it in the
marketing. Most DVD's on technique DO reveal what gimmick they are teaching technique for, as
opposed to a new gimmick. This is a technique for a gimmick that was really pioneered by the likes
of Michael Ammar. In fact, his method is really not too different from that of Michael's. Michael
uses his mouth and Diego uses a different part of his head. Also, the DVD doesn't show his face for
the performance. Given the method he is using, it would be beneficial to see how he moves his head.
