What others have been saying:

“Arthur has created a wonderfully deceptive peek that is 100% impromptu and angle proof. Something for many years I have been searching for and have finally found!

Review:
1.  This is great! Easy review. Definitely a cool idea. Can be used to peek anything written down on a business card and put back in the business card stack. For sure will be on my mind

2.  Love this peek. Invisible, motivated, full billet peek from INSIDE the stack. Oh and no knacky or weird moves. You will love this and you will use it for the rest of your life. Yes you can use double blanks, business cards, borrowed business cards, billets. 

If you use business cards or billets and need a clean, invisible peek (who doesn’t!) then you will like this. It’s a solid, useable and simple. It’s also very cheap. Buy it now. 

3.  I purchased this effect direct from Arthur and not from Penguin after stumbling upon a thread on a magic forum. The mechanics of this peek can be learned very quickly, it gives a full view of the card and is 99% angle proof. It's beauty is in it's simplicity like many great effects in magic. Unlike a previous reviewer I see no problem with returning the card to the centre of the stack to 'isolate' it and with proper framing neither will your spectators. Without doubt this is the best value full card peek out there.

4.
Just like the previous reviewer, I didn't buy this peek from Penguin, I got it even before it was released here. 

It's one of the best, if not the best, peeks I have ever learned. There are no moves. No sleight of hand. Nothing suspicious. Yet you get a full peek. I am very happy with it and I highly recommend it.

5.
I bought this elsewhere before penguin released it, but just saw it pop up on the homepage. It is what I believe is the perfect peek. Every action is justified and completely invisible to the spectators, the method is so simple I don't know how I didn't come up with it myself. 

I will be using this peek for future performances guaranteed and I'm sure if you buy it you wont regret it. 

Well done.

I know a LOT of p**ks and this one stands out as being one of my favorite in the quick p**k category. If you offer a bit of palm reading, you can p**k for longer. ;) 

It looks and handles so clean. The beauty is in the simplicity. You don't have to go through a ritual of moves to get the info. Everything in the ad copy is true. I love folded "card" work, but I like the card to remain open when possible. 

I almost didn't get this because I didn't think I needed another p**k, but I'm very happy with my purchase. This is a technique that I see myself using for years to come. 

and so on
