This trick is 5* in design and in theory --- but in reality
it is almost 0*, because you can't use it unless you have 20/20 eye sight, or you can easily identify an 8px font size
dot shape from 2 feet.

If you don't have such eye sight --- then it is almost a junk,
the most you can do this trick is to a person sitting next to you by a bright table top.

I like this effect. It gets a strong reaction. And while you can do it with ‘regular’ cards, I feel the ESP symbols, in their simplicity, actually make a stronger impact. Also, it helps this card trick feel less like a card trick.
I have one issue with the cards themselves that I can’t really get into here without exposing something. And while this is pretty easy to do, and a strong effect, I would say it’s not for everyone. Now, to address the only real problem with this trick: The instruction. Details on a key move that, in my experience, has been needed far more often than not, is glossed over at best. Discussion about the gimmick(s) is also scarce. There aren’t any alternative handlings taught, though I think it is important to do so with this trick. The instructions seem rushed. Like they weren’t scripted or well thought out. As if there was a rush to get it marketed with no regard to providing value for the money by way of instruction detail/quality. I also think that, for the price, (and particularly given the rushed and lacking instruction), the set should’ve come with either two sets of cards, or at least an extra key gimmick which makes it all possible.
I would’ve rated this a 4, had it come with two sets of cards/gimmicks; and a 5 if the instruction was comprehensive. It’s a good, strong trick. Poorly taught and, in my opinion, not with the price for what you receive.

I do a number of different effects involving matching ESP cards, which may look a bit similar, but want a range of options for presentations, so this is a valuable addition. If I'm with a group that may have seen a different effect, it lets me avoid repeating exactly the same effect for them again too soon. The handling and approach is good although I'm weighing thoughts about alternatives to the one sleight needed -- others have suggested alternatives as well. I personally prefer an audience-member-as-psychic approach for all of my effects, and it's easy to turn this presentation around. Instead of having the audience member think of a symbol and trying to guess it, my presentation will have ME looking at a symbol and putting it down and asking the audience member to try to get an impression of what symbol is in MY mind and putting down that symbol. I have found that this approach always eliminates the challenge response of a spectator trying to catch the performer out and make the effect fail, instead giving the spectator the motivation for the effect to succeed, and they get the "win" when it does. Participants never feel like the performer has one-upped them or put them down in any way, and the audience still knows who is responsible for the success of the effect.

Wow, it’s pretty rare to come across something like this. Not only is this super powerful, but it is also so simple to perform. When it comes to my everyday carry I typically don’t like to bring more than a deck of cards and a few coins with me. But this will be coming along as well from now on. I can’t recommend this enough. It’s a killer.

I don't do mentalism. So you may say, "Why would you even think of doing this?" Well I liked it. Plus my routine goes just a bit different and talks about my influencing them. In any case, it's well thought out. It flows. I've shown it to a couple people just to get the feel of it and I was very happy with the feedback I received. Truly blows them away.

Now that I've gotten the initial idea of why I'm doing this, it's time to wear out the first set of cards in front of the video cam to make it the masterpiece I think it is going to be.

Thanks.

Well, I agree with some of these old comments, but the main problem of marked cards being hard to see can be fixed with Tenyo ESP cards, which can be deciphered easily from distance and in bad lighting conditions… as far as being left dirty with the gimmicks, the spectator has handled most of the cards and has no reason to examine your pack … the clean up move at the end is invisible to onlookers… relax, this is the best ESP matchup effect out there IMHO and I still use it

Highest recommendation! Easy to perform, high quality ESP cards and the best reactions! There's only one minor sleight that you need to do and you only have to do it half the time (buy it so you'll understand!). The move is super basic, not hard at all. Cards are examinable. They can choose either red or blue. The fact that you always put down a card first is the strongest part of this trick. As always you need to practice this and of course know your spectators. Buy it now!

The combination of methods makes this a very clever fooler. Not entirely self working but not difficult either. John George glosses over a couple of the moves in his video explanation but you'll figure it out. It's a brilliant routine,and the cards are beautiful. This is a solid worker and I plan on using this a lot.

Wonderful mentalism effect. Easy to do. One slight you might have to do 50% of the time but very easy. I use it at my restaurant. You can reset it in front of audience. Need to wear my glasses in low light but no problem. I bought 2.

A very direct mind reading routine.
Once you understand the workings, you can use your own ESP deck. I use Eclipse since it makes it easier for me.
You can replace some moves as you see fit since the DL is weak in my opinion. A strike second is more appropriate.
Regardless, this is a winner.
