Stage Flavor Cartridge Variety Pack with Electrolytes and Stevia, 6-Pack (2 Strawberry Watermelon, 2 Tropical Punch, 2 Blackberry Twist)

I am not a water drinker, but with this system, I have drank a whole lot more water each day right now I’m using the fruit punch flavor, and I like the idea of dialing the amount of flavoring that goes in my water

Great price and great flavor. They also last as expected.

Not much a fan of these cartridges. My daughter bought me a Cirkul last year and I use it all the time. I saw these cartridges using Stevia and thought I’d try them, but in all honesty, the water taste like it’s been “water down,“ and there is very very little taste so I’ve gone back to using the regular cartridges and I love those flavors, so in general the regular cartridges, get a five, but I won’t be using these ones again. I tried all of them to make sure that I didn’t have a dud. They all had close to zero taste and the little taste that they did have was “odd.” No biggie as Cirkul’s regular cartridges are FANTASTIC!

Wife loves these. Good flavors.

Not all Cirkul cartridges are created equal. The only thing I can see that is different is is that these have stevia for the sweetener instead of sucralose. But the flavor is not there. I didn't like the blackberry at all it was kind of a medicinal taste and the fruit punch was okay but I had to turn it way up, it seemed awake I haven't tried the other one but I won't be ordering this group of flavors again.
