I recently ordered 'Just Think' as I had seen it performed and thought I had to get one,and it arrived today and i am actually quite pleased with it.
The effect is that the spectator is asked to think of a card and write it down on a post it note for future reference and then scrunches the post it note up so the magician can't see,the magician then looks through the cards and decides on one which when revealed is the correct card the spectator thought of!NO FORCES,ANY DECK ,ANY PIECE OF PAPER,NO SWITCHING.
The gimmick itself is a delicate thing but easy to use. I would give the trick a 4 out of 5.

I ordered it from freepostmagic , My order arrived the next day,so very good
