What I like about this product is the taste. It has such a great flavor and you get that feeling of energy it’s highly effective. You may experience a small crash though later in the day after drinking one the ingredients are pretty natural compared to other drinks and there’s not a ton of sugar in it. The packaging was really simple and easy easy and it’s a great size. It’s a lot bigger than your typical Coca-Cola again and it’s completely affordable. You can find any flavor that you want.

I tried the watermelon burst flavor and it tastes like a real watermelon!! Not that artificial flavor you usually get with watermelon products. It’s actually really good compared to other energy drinks with worse ingredients. I like that this is a healthier alternative and you still get that boost along with other benefits.

First time trying this product + I was pleasantly surprised by the burst of energy it gave me along with a nice taste. I don’t typically go for energy drinks, but this one has me changing my mind - especially with all of the great benefits it offers. I love that it is zero sugar + offers 200mg of caffeine, that’s exactly what this mama needs! The flavor is pretty good just not my favorite (which is my reason for 4/5) but I’m excited to try other flavors that may fit my taste buds better 🙂

Another delicious C4 flavor!

I've tried all the C4 Smart Energy flavors, with my favorite being Electric Sour. Electric Sour's blend of mild sweetness contrasted with tangy lemon and lime was delicious. I really enjoyed C4 Energy Midnight Cherry, and to hear about a Smart Energy Black Cherry was awesome! Compared to Midnight Cherry, I found this Black Cherry had a bit of a tart cherry flavor which helped balance the sweetness.I didn't experience a significant increase in energy or awareness after drinking a portion (6oz.), but I do have a high threshold for caffeine. The carbonation level was medium to medium-high, which I enjoyed (I like a higher carbonation level).On taste alone this is worth the purchase!

Best energy drink out there

As someone who has ADHD, typically most energy drinks don’t have much effect on me, or they just immediately make me tired. This is the first one I’ve tried where I haven’t experienced that, I genuinely feel like I can run through a brick wall, and I think that’s in part due to the fact they don’t use synthetic caffeine, if you check the label the caffeine is 100% from natural green coffee beans. Highly recommend if other energy drinks haven’t worked for you.

Delicious focus

I was selected to recieve a free case of this product. For some reason it never showed up probably due to covid. So I bought a few at the local store. I really enjoyed the flavor with the carbonation. Smooth real taste not that fake flavor you get from other RTD. The main reason i bought this was to have focus and energy while working on the computer. There was a very good clean focus and noi jitters. Cognizin is used for mental focus and clarity and mixed with the right amount of caffeine it really works well. I felt like they dosed this properly and it kept me on task without to much energy where i needed to go for a run.

One of the best!

C4 SmartEnergy is one of the top, if not the best, energy drinks I've had (and I've had more than I'd like to admit). I recently had to make the transition to night shifts, working long days on minimal sleep, these have been a lifesaver. They taste great-my favorite is electric sour which is the tastiest take on sour gummy worms that I've had to date. It is tart, refreshing, and flavorful. That being said, the other flavors are on point as well. The energy boost is great; with 200mg caffeine it allowed me to stay focused and not doze off without any crash. They are sugar free and calorie free as well. Definitely worth a try!

Pre-Hustle

I love this drink. Daily, it serves as a mental queue that it's time to get to work. With 200mg of natural caffeine it gives a perfect boost to get the morning rolling or as an afternoon pick me up.Cotton Candy isn't my first choice but what was in stock and it's a really nice flavor. (Very similar to the Bang Cotton Candy but less syrupy.)It works fast and lasts with noticeable effects for 2 1/2-3 hours.I couldn't tell if it was placebo or real effects at first, but going on a week of daily use there is definitely an additional element from the everyday energy drink to help you focus and process information.Bottom line: I'd recommend to anyone.

Yummy

I was looking for my regular cotton candy energy drink but unfortunately they were all sold out so this one was on sale and I tried it and it was amazing! It kept me going all day without like that crash or feeling like I’d actually drank an energy drink. Also, the flavor is Very good. It tastes like what it says it is. Highly recommend!

really good taste; great boost; gradual let-down

I thoroughly enjoy this drink. The taste is exceptional; I don't think I've ever had a carbonated drink to taste so good! Additionally, the pump/boost is immediate and last throughout the afternoon for me. Further and probably most importantly for me, the energy decline/letdown is very gradual as opposed to a sudden energy crash. Now, I bring in a caution, but this caution has nothing to do with this particular drink, in my view. Though I do have trouble with sleeping with little to no caffeine, I experienced greater trouble with sleep on days that I used the drink due to the high caffeine content. So, please beware of this potential problem.
