Monster EnergyUltra Fantasy Ruby Red, Sugar Free Energy Drink, 16 Ounce (Pack of 15)

I really like this Monster! The ruby red grapefruit flavor is light and refreshing, and it’s a great zero-sugar option. It gives me a good energy boost without being too heavy.

Most sugar free energy drinks have a weird aftertaste. Monster ultra doesn't have this. I have tried and enjoyed every ultra flavor out there and always try new ones as soon as they're released. This flavor is by far my favorite. It's not overly sweet. It has a very smooth flavor and one of the best parts is that it's not at all overly acidic like many energy drinks. I will continue tk buy this flavor.... Unless monster releases a new ultra flavor that surpasses this one. Which will be extremely difficult to do.

One of my go to flavors, bold ruby red grapefruit taste.

Awesome product just what I needed.

love this stuff. the flavor is amazing and never have an issue with calorie count. great quality

Ultra Fantasy Ruby Red is a great new flavor -- not too sweet or too tart and very similar to grapefruit without the sour. To note: they do not actually have grapefruit in them (in case you are taking BP meds).Biggest drawback (like all the Monster drinks) is it is too expensive most of the time. This is definitely a luxury purchase if you can afford to buy them regularly. I buy them only when I see a coupon or a decent sale price.

My favorite monsters EVER!! I love the flavor!!!! Some times they're hard to find so I order some

Cheaper than any store if you drink regularly!
