I've seen and owned just about every kind of impression pad. Each method has its advantages and
disadvantages. I had no idea exactly how Cogni worked until I got it, and then I struck my forehead
with the palm of my hand and said to myself, "Of course. This uses a gimmick that Richard Osterlind
taught on one of his DVDs. I think it's from Al Mann." Yep, it's an old concept, but applied to
these normal-looking little note pads, it's pretty much the bomb. The imp is excellent, and you
don't need a special pen and a m*****. Or pricey electonrics.
You're basically buying $10
worth of stuff and the other $25 goes to learning the secret because once you play with this, you'll
easily be able to make your own for about $5 a pad from Amazon. Sure, there might be better gimmicks
of their kind on the market, but for this price, Cogni is fantastic.
I've made up a
stockpile of gimmicked pads, and I'm keeping them all over the place--in my close-up bag, at home,
at the office, in my car, in my pocket... And why not? I'll always be able to do some great
mentalism anywhere I am. You can't beat that.
