this is the greatest card change on the market a would make this your next purchase along with the ungimmeked sleeve

Just brilliant. I'd strongly recommend buying the unfaked version at the same time - the mobile phone picture routine provides a perfect opportunity to swap them out. I don't ask the spectator to examine it but simply put the non-fake on the table - no one resists picking it up. Also since you can operate the change by a very slight movement if you hold the corners of the long edge between thumb and first finger you can put a spooky video on the spectator's phone if you use it to show the card eerily appearing as you bring it up to their forehead and fading as you move it away. Totally freaks them out!
