Buy these !!! They are delicious !!
Flavor Name: Barista Flavored Pack, Size: 10 Count (Pack of 3)
Seriously I can’t say enough how excited I was to find these on Amazon. I’ve been buying them weekly from target, which you get eight of them for $14 and I just thought in the long run this was a better deal and let me just mention the flavors are so delicious every single one of them even adding cream or creamers you can distinctively taste the flavors of this coffee. I’m obsessed. I drink them every single morning.

I FINALLY found the perfect flavored water!
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
I initially ran across this water b/c it was on sale at my local grocery store and it was NOT what I was expecting at all! I genuinely dislike drinking plain water regardless if it's from the tap, filtered in any way or bottled, regardless of the brand. I will only drink regular water if I absolutely have no other choice.
Over many years I have tried numerous types of flavored waters (regular or carbonated), flavored electrolyte drinks, flavor packets or dissolving tablets, etc. If it's out there I've probably tried it. I am also very attached to sugar, so I didn't mind if they were heavy on the sugar/flavor profile, but I was still looking for something that was more on the pure water side as it's healthier, but also something that would quench my thirst and hydrate me instead of leaving me feeling like I needed more.
I will, at times, order water w/ a lemon wedge and do have some packets that give a very light flavor of lemon or orange in comparison to everything else I listed above. For some reason these were "sufficient", but still not what I was really looking for.
HINT says it all in its name. It gives you a perfect amount of infused flavor rather than syrups, powders, artificial flavoring, etc. It will definitely throw you off for a second the first time you try it b/c it truly isn't like anything else out there that I've tried and is delightfully unexpected. The first time I tried it I THOUGHT it was going to be a disappointment b/c initially I thought it tasted like regular bottled water. Where is the flavor here? But in a matter of a second I tasted the infused flavor profile and it was wonderful. I went around my house and had others try it, knowing they were expecting the same thing I did, and they too were impressed and surprised.
I am still amazed at the way this water tastes and I now order by the case. Because this water is so perfectly balanced and refreshing I have almost completely stopped drinking anything else. For the past 6 weeks or so I have continued to only drink HINT (admittedly I have purchased 2-20oz bottles of soda as a treat), but I do not have any desire to drink anything else. I actually drink water now, and I can't believe I'm saying that.
If you are a water drinker that wants a little bit more, I suggest this product. If you are like me and have spent decades looking for water that is flavored, but still hydrates and refreshes like regular water, look no longer. HINT is unique and bottled perfection.
For people who are conscious of the planet or your body is a temple, HINT also holds a gold standard. The bottles are BPA-free, making the bottle and cap 100% recyclable. Ingredients are only purified water and natural infused flavors. And there are a lot of flavors to choose from. HINT is vegan and free of sugar, sweeteners, MSG, nuts, soy, gluten and preservatives.

⭐ ⭐ ⭐ ⭐ ⭐ Refreshing flavored water with zero sugar and clean ingredients
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
⭐ ⭐ ⭐ ⭐ ⭐ Refreshing flavored water with zero sugar and clean ingredients
I decided to try the Hint Infused Bottled Water Best Sellers Variety Pack 16 fl oz Pack of 12 because I was looking for a healthier alternative to sodas and sugary drinks. After finishing most of the pack, I can honestly say it has become one of my favorite everyday beverages.
The flavors are very light and refreshing, which I personally prefer. Instead of tasting like artificial sweeteners or syrup, the water has a subtle natural fruit essence. It feels clean and crisp, making it perfect for staying hydrated throughout the day without extra sugar or calories.
I also like that it contains no artificial sweeteners, zero sugar, and zero calories, which makes it a great option for people trying to reduce sugar intake or follow a healthier lifestyle. The variety pack is nice because it allows you to try several flavors and see which ones you like most.
The 16 oz bottles are convenient to grab on the go, pack for work, or keep in the fridge for a quick refreshing drink.
Pros
• Very refreshing and light taste
• Zero sugar and zero calories
• No artificial sweeteners
• Good variety of flavors
• Convenient bottle size
Cons
• Flavor is very subtle (some people may prefer stronger taste)
Overall, this is a great option if you want flavored water without sugar or artificial ingredients. I will definitely keep buying this variety pack to stay hydrated in a healthier way.
