The cans for Relentless Energy Drinks say "Conceived in the U.K., Born in the U.S.," and the can of orange "Fire" flavor we tried included this quote from Benjamin Franklin: "Energy and persistence alter all things."
The "Fire" flavor is very potent and super sweet -- imagine drinking melted orange popsicles or carbonated orange Kool-Aid. We didn't find the flavor too overpowering, but we've always had a sweet tooth. Our drink was cold, too, which makes a difference. Relentless probably doesn't taste very good warm.
