I don't understand the need for the stealth adapter since the glass looks like a straw and can just be put through a cup if that is what you want to do. To me the solo with your hands over the light looks like a can anyhow and if you wan it more stealth print a red bull label and put it on and cut out the light indented section and keep that on your palm side. You can even use one of those drink holders that are made out of neoprene. Just my thoughts.
