I'm on a keto diet so I use this twice a day and it works great! Just pop a tab in glass with 8-10 oz water, great subtle flavor, no sugar! Absolutely LOVE the packaging! No messing with pouches or scoops! One sleeve has 10 tablets, so just plop it in my bag and I go about my day, not worrying the pouch will tear or open (has happened with other sticks!). Simple. Love it. Can't wait until they have other flavors, but I'll keep drinking this one indefinitely.

Taste good

I like the flavour, not too sweet, the only thing is they take a while to dissolve

Weird taste...and no fizz....

I presume these do what they are meant to do...replenish electrolytes (although how completely you need replenishing, meaning needing other minerals besides what are in these Idk) However, the whole reason I would not repurchase is the taste is ...OFF. For some its not that strong, but for me its TOO strong, I want a subtler lemon lime taste (or any other flavor) basically a sugarless Sprite taste. And if you're looking for fizz to truly make it a flavored seltzer water experience, Nope.
