What do you guys think about the mind power deck?

I got the mind power deck, and I found that sometimes people know that the the deck is extremely gimmicked! But other times people are so amazed the don't say anything for the rest of the day...
It's a very powerful effect but (as in every trick) presentation is the key. Once a just spread out the cards and read the minds of two people, and I didn't get very good reactions. But another time I made up a whole story and I got massive reactions!!

How do you guys use it, and how do you feel about the quality of the trick? let me know
