Usually I find watermelon flavors too sweet in candies and drinks, BUT the Madrinas sour watermelon has that sour to balance it out! This negates the cloying sweetness I usually associate with watermelon flavor -- it's much more refreshing and bright. I think they may have hit on something great with this one!
I recommend blending it into your own homemade watermelon slushie if you have a blender at home. Add some fresh or frozen watermelon chunks if you're feeling fancy. Perfect for enjoying outside on a hot day.
