So im tired of buying overpriced gear that is misleading from the ads and description you get before you buy. Flux is 200$ and i already have a gimmick wich cost me 5$ that seems to do the same effect (its i thumb tip with a small magnet you put in and can feel it move around when you approach a metal ball the spectator holds in their hand and you guess wich hand its in) soo how is this 200$ gimmick worth it? First the only reason i wish to buy it is because it says you can tell wich side up the quarter is... Wich is a bonus but does this work only with a gimmicked magnetic quarter ? Would a canadian quarter work as well since they are already magnetic? I know its off rules to give away method but if i already know half of how this works can someone please give the details of how the heads up or down side of this works before i waste my money on something i probably dont need??
