Overall rating: 2.7 / 5 from 49 reviews.
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.
Very tasty, I like the slight carbonation. Arived on time!!
Very Tasty, and gets me through long days on the field.
HI 02 TEAM THE DRINK IS VERY GOOD I LOVE THE TASTE AND THE NEW 02 WATER IS SO REFRESHING. I LOVE THE STRAWBERRY LEMONADE FLAVOR. I GIVE THEM BOTH FIVE 🌟 STARS. THANKS ADA MILLER
Great!
Customer service is exceptional! We love the drinks. But miss the old formulas and flavors.
My kiddo likes these before his sports and in mornings after late night games
I hate the new carbonated beverage, and I am very disappointed that the only non-carbonated options have no caffeine. You have lost me as a customer. So disappointed.
Love the taste, keeps me officiating Football through the day!
I loved the original Orange Mango and am very disappointed that it has been discontinued and replaced with a carbonated version. I,! also, miss the Grapefruit Ginger. The current carbonated caffeine versions are terrible. The Orange Mango is just tolerable and the Cherry Cola is terrible. Please bring back the uncarbonated Orange Mango and the Graoefruit Ginger. I subscribed to both. I will not subscribe to the new carbonated drinks. I bought all of the old versions I could find on Amazon and at my gym after they were no longer on your website. I will be sad when my supplies are depleted. I have been a loyal customer and am very disappointed with the changes.Reading the other reviews, I see that I am not alone. Also, please bring back the powdered individual packets of Pomegranate Guava and Peach Pear. They were wonderful when I traveled and could take my O2 with me. Please listen to your long standing customers .
Flavor sounded good but the taste was just Ok.
Terrible unfortunate that O2 decided to go this route with their lineup. I LOVED the Orange Mango and especially the Grapefruit Ginger with the OLD formula. I decided to give the new Orange Mango a try and man I'm so disappointed---it's just not good at all. And what's crazy is that this new formula lives me with a "fake" taste in my mouth...which was a huge benefit of the old stuff. Please, please, please listen and read these reviews---there's so many of them. Go back to the old flavors and stop trying to be something to everyone. Signed...unfortunately, a former O2 fan :(
I enjoy the taste and the bubbles.
Like O2 but would prefer other flavors
Excellent quality energy drink.
The old Orange Mango formula was much tastier.
Go back to the non carbonated energy drinks!
It’s not oxygenated.
I was extremely disappointed to discover that this product is now carbonated. Due to a health condition, I am strictly unable to consume carbonated beverages. Because of this unexpected change in the recipe, I would rate this product 1 out of 5 stars. Changing to a sparkling formulation without prominent notice makes it unusable for customers with medical or dietary restrictions regarding carbonation.
Bring back the Original Orange Mango it was much better !
I prefer the original orange mango to the new iteration. I really miss the grapefruit ginger. I tried the new waters (strawberry lemonade and tropical pineapple), and they’re ok. I don’t like any of those products enough to continue my subscription, and will be canceling.
Bring back NON-carbonated
New flavor is terrible. Used to love the old flavor and had a subscription for years, canceled as soon as I tried this. Please bring the old orange mango back.
Do not care for the carbonated orange mango. Sad to see you discontinued the original product. We ended up canceling our subscription after 7 + years since you no longer carry it .
Bring back the original orange mango, please!!!!
Completely different from their original orange mango drink. The other one was so good, this is a terrible replacement!
I loved the original O2 orange mango so I was hoping this would be similar. Unfortunately it’s sweetened with monk fruit and that upsets my stomach. I find this has an aftertaste. I would love to have the original again
I swapped to this flavor because they stopped making the Orange Mango flavor without caffeine. This energy version tastes fine, but I prefer the discontinued drink for both flavor and lack of carbonation.
I prefer the older Orange Mango flavor MUCH more than the new. The new flavor is too sweet and strong.
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!
Very Tasty, I really enjoy the light carbonation!
It was damaged. One can. Completely sprayed out.
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.
