(I'm not showing as a purchaser because I got this on Open Box auction).

As usual with Mickael, he seems pretty pleased with himself while glossing over any problems his mechanical effects may have. "It's invisible! It's perfect!" While the gimmick is as perfectly constructed as possible, it does show in certain lighting scenarios, and in fact shows a few times even in the video. Not "invisible", but I think some handling adjustments can deal with that. The big problem is the noise this thing makes when switching, which is amplified by the empty card box. You'll need both distance and significant ambient noise to cover, which obviously limits your opportunities to perform it. Mickael does not address the noise issue AT ALL in the video. To his credit, he does not mute the noise in his video. The result is a bit comical as he performs the switch, and every time the noise blows the effect. I am going to try to redesign the gimmick with some padding and slow down its operation. It won't be usable for the visible instant switch, but as-is it can't be used for anything in most environments except a very loud club.

The description says "No manipulation." That's ridiculous. You need to either force a card, or control a selected card. A secret card fold is useful, but not required. You need to finger palm. Mikael doesn't teach these easy sleights in detail, but touches on them briefly. Anyone who would use this device probably doesn't need a detailed review.

The video is fairly easy to follow, and filming and editing are acceptable. Some variations are briefly suggested. The effect should be very hard-hitting, but as presented doesn't capitalize on the potential the gimmick offers (again, assuming the visibility and especially NOISE issues are addressed). I'll come up with my own presentation and I suggest you do the same. The card box must stay out of the spectator's hands and you are ending dirty. I think when I redesign the gimmick it will allow for putting the cards back in the box and putting them away while attention is on the signed "prediction" card.

Not for everybody for sure, but recommended with reservations. Obviously a lot of time must be invested in making the gimmick, but the price is still high in my opinion.
