Considered the King in this Zero Sugar division of Monster by many and understandably so because as soon as you taste this it unlocks a memory.. That memory is the taste of Sunny D, just with carbonation.

This is my favorite energy drink. Period. I look forward to drinking the zero sugar white canned Monster every Thursday, as a treat to myself having to go into work (hybrid worker).

I love the monsters energy drinks but not sure how long I can keep buying them, the price keeps going up and is almost as expensive as buying them anywhere else

I buy the Monster Energy Zero Ultra for my son in-law who will only drink this kind. He is fit and trim and appreciates the bold flavor with zero sugar and only 5 calories!

Tried every Monster energy drink and always return to Zero Ultra. It's the only one to never disappoint on flavor and crispness of taste consistently.

I drink monsters everyday but now they have become way too expensive. But the product overall is a great tasting drink. I don't think I'll be purchasing them anymore 42. And some change is more than I care to pay.

Monster Sugar-Free delivers the same bold, classic Monster flavor without the sugar. It’s smooth, slightly sweet with a hint of citrus, and packs a solid energy boost thanks to its caffeine content. Great for those who want the kick without the calories, though the artificial sweetener taste is noticeable. Overall, a strong choice for energy without the sugar crash.

Good value compared to buying them in the convenience store.

It is a white monster, it gets the jobs done.

This is the only flavor I consistently buy.
