Hello,
This is my first review so lets be gentle now

The Effect
What Paul says ::
The performer removes a single folded post-it note from his pocket. There is nothing else in his hands and he can show both hands to be empty except for the folded post-it note.
He closes his hand around the folded post-it and keeps both hands in full view the entire time.
The participant freely names any one of thirteen drinks. She takes the billet, and opens it and the only thing written on the billet is her chosen drink.
Being a utility gimmick you will be able to use up to thirteen of anything for the participant to select. You are not limited to drinks!

Review
So I bought this by mistake..it was 3am..I was tired..what you guna do? Anyway I'm so glad I did, heres why. The description of the effect from Pauls site is pretty accurate. In fact its spot on apart from one tiny bit which is pushing the boundaries of imagination - but thats me being petty, and technically it is 100% accurate.
This isn't so much of an effect as instructions and ideas for a gimmick. The amount of effects you could perform with this information must be into their thousands. The gimmick used is originally for magicians but Paul has adapted its use to create some great mentalism or mental magic. The possibilities are endless, so it really is one to get your imagination working. You also get 7 great effects to perform with it.
You get a lovely 63 page E-book e-mailed soon after payment with full performance scripts, method & instructions, references and subtelties and the 7 effects I already mentioned.
It is impromptu in the same way any card trick is impromptu if you have a deck of cards with you. It is not "naked" mentalism. However, the gimmick is small enough to carry in a pocket, bag, or bra if you so wish. It fits nicely in my tight jeans pockets with room to spare. Because of this it is brilliant for close up and walk around mentalism, It could be used on stage but perhaps a little more thought would be required.
As mentioned on the site you do have to buy something extra. This something "extra" is the gimmick itself, this cost me £12 from a UK online magic store. However, due to it being out of stock it has taken five weeks to arrive..that was a long wait - this is nothing to do with Paul though, however you should bare in mind that you arnt going to be able to perform any of this manuscript without this gimmick. Once the gimmick has arrived it needs to be altered with a bit of DIY, this is perfectly easy and took me about 15 minutes to do and is covered in great depth in Pauls E-book.
In total the whole effect has cost me ::
£15 for gimmick + post
£15 for "the "Underhanded" E-book
and £2 for paper.
So unless you already have the gimmick the effect is going to cost you in the region of £30.
My only issues with the actual effect is that it cannot be performed surrounded. you will have to be careful with angles when you perform, unless your good with your hands

I have performed this around 15 times now and it gets great reactions every time. I've come up with about 5 different effects which play very differently. I've even used it as an element to force a word on a spec in a completely different effect. Pauls E-book turns a good magic prop in to a fantastic, workable and clean mentalism utility. I would say the E-book is slightly overpriced. I would have been tempted to knock it down to £10 for the sole purpose that you still have to order the gimmick from a supplier. But then again, the idea is worth the price of so many other effects out there that this gimmick could save you alot of money!
To compare with another of Pauls products "The Thought Reader Card" I would say (if you cant get both) go for "Underhanded". Its possibilities are vast and you have loads of effects in your hands.... literally.
"Should I get it?" - Depends what you do. Its great for walk around mentalism. Its possibilities are endless. It can be used to predict or force and looks very very clean. It could be performed anywhere.
Paul goes through the script, method and subtleties in amazing detail. His words of wisdom are just brilliant. In the E-book you get everything you need + so so so much more. If you want a very clean "I know what word your going to say before you say it" effect then you need this!!.. This is mind reading at its cleanest.
Overall
8/10
