Love the drink. The old one was better without the fizz. However, this is a great pre workout/sweaty day drink!

Has good flavor, but I am personally not a fan of the carbonation and decrease in electrolytes with the new formula.

Still tasty, but prefer the non-carbonated version.

Horrible should not have changed to carbonated tastes like crap. Standard mango and grapefruit were fantastic was buying numerous cases a month, I won’t buy anymore with your new flavors being carbonated higher caffeine horrible tastes.

We love the Orange Mango O2 so we were super excited when one of the O2-Energy Drinks flavors was also Orange Mango!

I did not enjoy the new carbonated option. I will miss the non carbonated original energy drink.

One of the main reasons I love O2 is the non-carbonated, clean caffeine, and great taste. The new version is ok, but I'm not a fan of the carbonation. I like the caffeinated boost before a workout from the previous version. Having bubbles in my belly during my workouts from the new carbonated version isn't great.

I love love the original orange mango and am so sad it was discontinued. Bought a case of the new formula. Do not like the taste or fizz so I am stuck with it. Please let me know if you ever start making the original again, Thanks!

Tried to get used to the new taste, but couldn't. Tasted like Tang from my youth (hated it). Enjoyed being a customer for years. Wish the company continued success.

Changed the taste completeley. I have pulled my subscription after ordering 4 cases every month since 2020. I will no longer be an O2 drinker with this recipe in place.

So so disappointed in this carbonated version. The orange mango beverage was perfect before this. No carbonation, no aftertaste. This one is terrible

I don’t like the New orange mango
Eric O. 1/5 Verified
Didn’t realize that this flavor had been switched to an energy drink when I ordered it. Very disappointed. Will no longer be buying from here considering all the products I love are no longer sold.

Great replacement for my typical afternoon drinks to perk up a little!

It’s good but I really miss grapefruit ginger! Please bring it back
Stephanie D. 4/5 Verified
I do not love the new formula. Tastes more like a seltzer and more carbonation than the prior formula. The prior formula was MUCH better! I won’t be reordering.
