Love the pineapple

Great taste.

Delicious!

This tastes like Hawaiian Tropics suntan lotion smells. Feels like a huge miss after the amount of time has passed that it took to get new flavors. Brand seems to be moving in the wrong direction.

Both are smooth good tasting not overly sweet I love the pineapple a little better it's one of the best O2 has made both are excellent regardless the strawberry lemonade is smooth not too much of one fruit overpowers the other. 02 does it again
