You could give away too much. I believe that you would be safe if you showed your sales from using it and just using a "glimpse" of the stuff without having Chris wanting to track you down. So just figure if you were Cris, what would be acceptable for someone if they were reviewing my product and they bought it...so it is not acceptable obviously to leak anything inside to people who have not purchased it. I hope this helps but I would just place myself in their shoes. You could just mention what comes inside it ya know. Or hop over to youtube and embed a video that someone else has made.
