HINT WATER
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
THIS WATER HAS JUST A SMALL AMOUNT OF FLAVOR. IT DOES TAKE A LITTLE GETTING USED TO BUT AFTER A BOTTLE YOU WILL LIKE IT. IF YOU DONT DRINK MUCH WATER TRY THIS YOU MIGHT LIKE IT OVER TAP WATER.

Excellent if you like flavored water but not seltzer
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
I don't like seltzer but I LOVE this stuff. Minus one star because I think it's pricey. I could drink a bunch of these each day, but I limit myself to one.

Flavored Water I Actually Crave
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12), Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
I didn’t expect to get hooked on a flavored water, but Hint Water Watermelon has honestly become one of my everyday essentials. I usually get bored with plain water, but this hits that perfect balance, it’s just enough flavor to keep things interesting without feeling fake or overpowering.
The watermelon taste is super light and refreshing, like a subtle hint of a fresh slice rather than that overly sweet candy version you get with a lot of drinks. I’ve tried a ton of flavored waters, and this is one of the few that doesn’t leave any weird aftertaste, which is a huge win for me.
I find myself reaching for it throughout the day, especially when I’m trying to stay hydrated but don’t want soda or anything sugary. It just feels clean and easy to drink. At this point, it’s kind of replaced most other drinks for me. I always make sure I have a few bottles on hand.
