There are 3 things about Mind Invasion that I do not like:
1. As others have said, the
heat is on when you take your peek
2. The business card makes noise when you open it to
get your peek. Yes you can make some preparations to the card, but it still makes some noise.
3. The handling just does not seem natural or logical to me
Much better full business
card peeks are taught on Banachek's Penguin live lecture and Bobby Motta's At The Table lecture
