I just downloaded it's pretty neat and clever. It's a mentalist feat that utilizes a very basic mentalism principle. I have no idea why a reviewer would call this trick "Stupid". I wish he'd clarify more. Even aside from the effect itself, the principle you learn is awesome and you can use it to get your creative juices flowing. You'll need a bit of audience management as you don't want them messing with your stuff.

One note, though the trick is free, you'll need a standard card gaff. You'll find out what it is as soon as you order. This effect also works with the newer bicycle card case only, but it's fairly standard now anyway so it shouldn't pose as a problem.

This is such a stupid trick to put out even though its free. I will never use thks effect and even if you would you probably have known about this method in saw stupid magic kit. Just dont download it.PLEASE!

I did not personally get much out of this, but if you are just starting out in magic or mentalism, this is definitely worth taking a look at. And it's free, so you can't complain. If you have been into magic or mentalism for a while you might not learn a lot, but it's just a quick pdf file anyways, so it is worth giving a shot. All in all, a good product.
