Price Hike

Monsters are monsters...the price has been going up everywhere. It's getting to the point where they are better to purchase at a convenience store when there is a deal running. These used to be $19.99 on a standard shopping day...almost $25.00 now! There is also a taste difference from the ones with a silver top (the 12 packs) and the white tops which are typically found as a single purchase item. However, since I am already in the routine of this being a part of my morning I will keep purchasing. If it's not a part of yours...drink water instead.

Best Energy Drink Flavor Hands-Down

My favorite energy drinks (aside from Alani) however I still grab for these when an Alani flavor doesn’t sound good to me, because this Monster flavor always does! It never gets old. It’s light, crisp, citrusy, refreshing, bubbly, and so much more. I have one of these a day at work to get me through the day with energy, or more-so not getting tired. Best part? It’s sugar free. You can’t even tell!

Make it into any flavor or like it as it is.

This flavor is ideal to turn it into whatever you like. All you have to do is add a few drops of flavor drops such as Crystal Light or Kool Aid drops to the liquid and it becomes what ever the flavor you were wanting. I personally use grape and cherry. But I would imagine you could easily use orange, ice tea or lemonade. If you don't want to change the flavor that cool too because it has a really clean taste to it just as it is. It also does not give you any of caffeine side effects. It just keeps you going. I do recommend this Monster flavor.

These are my guilty pleasures. These give me energy but honestly I crave the flavor. I try to drink these sparingly but when I know a cold one is in the fridge its hard to resist. It has a good amount of daily vitamins too. It is expensive so I give up other stuff to have them

Well, it goes through it again like I said it was overall a good situation good understanding between the shopper and the customer knowing that we want fresh things and fresh things are what they got and I appreciate that cause they could've came back with the cans or anything, but they made sure I had the best produce in the best shopping stuff that they had to offer. Thank you, Walmart.

Beware, it's too good

I love it but its' very addicting so I can't recommend it. I am trying to quit drinking these really. This flavor has no artificial colors so it's the only flavor I buy but luckliy the flavor is also wonderful and probably my favorite of all the Monsters. Some other ingredients are not that healthy though.

Coffee Tastes Like Burnt Regret

My wife and I don't drink coffee. We've tried. We've given it chances. We've listened to coffee lovers explain notes of chocolate, caramel, and roasted perfection. It still tastes like someone filtered hot disappointment through a tree branch. Enter Monster Zero Ultra. This has become our official morning beverage. One can per day and we're ready to face work, chores, bills, barking dogs, and whatever fresh nonsense life has scheduled for us. The flavor reminds me of orange juice's energetic cousin. Not exactly orange juice, but if orange juice went to the gym, got a caffeine addiction, and started waking up at 5 AM to crush goals. The best part? No sugar crash. No giant coffee pot. No complicated brewing rituals. Just crack the can open and suddenly your brain remembers it has responsibilities. A word of caution: one can per day is plenty. Two cans and you may find yourself reorganizing the garage, alphabetizing the spice rack, and solving problems nobody asked you to solve. Five stars. For those of us who don't like coffee but still need to function before noon, this is liquid motivation in a white can.

Get that energy!

My husband used to spend so much on monsters at the gas station every day. When I found this and it could be auto shipped I was so excited. The price is great and we never run out!!!

Empty cans of monster

I love these- buy all the time, but in my case this time there was 4 cans empty inside carton , but the inside shown no signs of leaking, and the cans were unopened… But I love and buy weekly.
