Tonic Exotic Watermelon is not unique. It tastes very, very much like the other watermelon flavors on the market. In terms of real world comparisons, it’s about as close to watermelon flavored Bubbleyum as you can get outside of actually buying the gum. It does not taste bad per se, but it begs the question of who would want to taste bubbleyum for an hour and a half. The taste is somewhat like the real thing, but an extremely sweet (almost sickly so) caricature of the real thing.
