ACAAB has some rave reviews. I am, however, somewhat ambivalent... Boris Wild has a (cleverly shot) video on YouTube of him performing it live at FFFF. You can find it easily.
From that video, one can readily deduce the outline of the routine, though there's still one (off-camera) required move which can be accomplished in various ways, and I don't know what method Boris Wild is using to accomplish it. I'm not sure I want to spend $25 to see exactly how Boris Wild handles that move, but I'm not sure I don't either. (This move is, I presume (or hope), what Boris is trying to sell to magicians. And that has to be why he hasn't released a full performance, since if one saw him do it, it'd probably be quite clear what was happening.)
Since I know what's happening (even if I don't know the exact method), I probably won't purchase it until I see a full performance where I can see what's going on when the magic move happens. I would call the "no sleight" claim at least mildly dubious, though this might depend upon your definition of "sleight." Your mileage may vary.
As Josh has noted, ACAAB works best with formal wear (some might say it requires it, though that'd be going a wee bit too far), but this will be a downside for some. I don't like the marketing style behind the release of ACAAB. If you're afraid to show a full performance (as it seems to me that Boris clearly is), then you get an immediate vote of no-confidence from me. I weigh this vote of no-confidence against other factors. And in this case, I award Boris a non-zero sum of points which are still too few to get me to purchase his ACAAB.
