Ridiculous as this sounds, I'm tempted to give it a try. I like weird gadget stuff like this and the fact it's subohm means it'll ft in with my usual vaping method. I agree with the writer though, we need more info on what's in these 'flavour balls' before buying.
Different, but definitely a gimmick.
I like to vape 2 or 3 juices a day and achieve that with different tanks ... each with a flavour I know that I enjoy. Switching between 6 generic, plain flavours on a single device is not only a fix for a problem that doesn't exist, it presents a much poorer option.
