They only give you the option of more 7's and 4's (but in various suits). I don't feel this is enough to waylay a spectator's suspicion about the cards. Too much similarity just always using 7's and 4's. Please provide more two-card options in the packets. For example, in a 3 packet refill, provide other card denominations. Clearly the effect doesn't rely on them having to be a 7 and a 4 so the 3-pack could have a 3 and a Jack, an Ace and a 9 and finally an 8 and a 2 all with various suits. I realize this is more production cost but I'd gladly pay for this variety than risk the method to a spectator.

The refills are great and they do just what you need. Keep up the good work.

Tornado is so great !
I was immediately sold for buying a pack of three refill packs, at a very affordable price !
And I must say I was a bit disappointed, because there are only 4 different sets !
It would be an issue for non-pro like me, performing for the same group of friends, which could guess why there are only 4 and 7 involved in that beautiful trick (trick that they will remember, and that they will absolutly demand to see again, at the next family meeting... because it's so good!)
Why didn't you design a refill pack with more options? It could be an idea, and, if you're projecting to do so, I'm in!

IF YOUR GETTINT TORNADO, GET AT LEAST 1 REFILL PACK. I HAVE 9 REFILL DECKS AND STILL HAVE PART OF THE ORIGINAL PACK. THE 3 PACK DEAL IS GREAT. SO ORDER THE 3 PACK. YOU'LL BE DOING THIS ALL THE TIME, I KNOW I HAVE. THE TRICK IS POWERFULL BUT FAIRLY EASY. THE NICE THING IS YOU CAN CARRY SOME IN YOUR WALLET OR GET A CARD WALLET. I HAVE THE CARD WALLET AND IT HOLDS A LOT.

Bought it, love the trick, but it would be great (and I'd pay a little more as I know it would cost them) if they could add a few other suits and card numbers.

Tornado refills were satisfactory in their appearance and most importantly, their order. In their coming out of the box I was able to take them right off the front of the deck to back.I did not have the suits embarrass me coming out all miss matched and need to spend time straightening them out.

Last time I was busking, I got great reactions! Great trick, but I'm running out fast. haha. So thanks for making refills available. A pretty good price for this many refills.

This is a very cool trick. I like the fact that it is almost self working. It has the greatest punch line of any card trick I do. Will order more refills in a few days

I bought Tornado and realized it's awesome potential. So I went and ordered refills right away, knowing that I'd be preforming this trick often.

I am fast becoming a fan of Tornado and always keep it on me.

After learning the trick the first time, I immediately ordered three packs of refills (each pack allows you to perform the trick 28 times). I always carry two sets (four cards) in my wallet ready to go. (Though of course: we never show the same trick twice for the same person/s).

It is a clever trick that only requires you to remember the sequence of tears - there are NO complicated slights and it is incredibly deceptive!

I have had some of the smartest and most clear thinking friends sit there stunned at the end of this trick. "But how? I was holding my piece even before you started tearing up the second card!?"

A very clever, effective and enjoyable trick.
