FitSip 6-Pack. No Sugar, 0 Cal Flavored Water with Electrolytes

I love my cirkul. These are true cirkul flavor packs. I like the flavors. Drinking this helped me increase water intake and lose 40 lbs.

Great flavors

These taste wonderful they never leak my two autistic boys use them it was a great way to get them to drink water when nothing els worked .

Its a great water bottle. Great flavors.

These are great, the only downside is how fast they run out. One cartridge seems to last a 40 oz Cirkul tumbler about 3-4 fill ups on dial level 5-6 (for me, could vary for others and obviously dependent on a variety of factors). This means that fundamentally I am going through one cartridge every day to two days. I want to say one cartridge flavors 120-160 ounces, but that might be a stretch.With every cartridge being about $3.30, it's actually not that bad. Cheaper than most 20oz sodas these days and one box can easily last you a week, maybe a week and a half if you don't mind watered down flavor cartridges.Where things get expensive and kind of not worth it, is if you have a family. Me and my sister have one with my mother buying one too. That's roughly 3 cartridges a day, maybe 2 meaning half a package in one day. Even with just two people, one package will only last about three days. So these are ideal for the loner, or for yourself. But for a family, they're not going to be cheaper than a simple 24 pack of soda.
