I can honestly say that I use to drink LESS than 1 gallon of water a year! You read that right, lol. I now go through at least 2 gallons a week and my Dr said it is helping my POTS symptoms. People who have known me can NOT believe I now have a bottle of water with me. I cannot believe it myself after 62 years that I would be drinking water voluntarily. I recommend you to my, over 10,000, followers and anyone I know or meet wherever I go. This is so much better for my senior aged body than sports drinks and I am slowly losing weight without even trying. Thank you for a healthy outlook on life!

I like that there’s so many different flavors and I drink so much water now than I did before. One flavor cartridge depending on flavor for me does last about 6 refills sometimes more. Example I love the lemonade but I like it on the in between 3 and 4 so it might be 5 refills. I took with me to Disney trip put the Sweet Tea, then just filled up with water at the parks.

I bought this...but decided to try it by borrowing one from a friend to see how it would work for me. The flavor cartridge...even though I had it turned to between 0-1 only lasted me 3/4 of one day...maybe 6 bottles. I thought it would last longer because I had the flavor so light...but no. Replacement cartridges are like $4 each at Walmart (best place I could find). So I decided this was not cost effective for me and returned my un-opened purchase.

I started my all water journey about 9 months back and I was doing good but still found myself drinking sodas with my food. I saw the Cirkul add and decided to give it a try. 4 months now and I haven’t had anything else except plain water. This is the best product I have ever used. I recommend this product all the time. I have a bottle in my hand everywhere I go.

I’m not much of a water drinker simply because of the chlorine taste. I love this bottle. With my water filter and pitcher and Cirkul, I drink three times as much water as I used to. Not all the flavors I’ve tried are my favorite, but I have the ones I’ll drink all the time and wow! Very good!!

Doesn’t keep your water cold or cool. Would rather buy the insulated tumbler adapter than use this bottle. The cartridge is a little noisy, needs better airflow, IMO. I do like the flavor cartridges and the wide variety of flavors to choose from. I keep mine dialed around 3-4 and it will last for 3 -4 fills. It definitely has me drinking more water now.

Bottle is so hard to suck water out of, no beathing hole.

Is an awesome water bottle and great flavor you can adjust how much flavor you want

The concept is great but the flavor doesn't always come out

This straw is very difficult to drink out of. The flavors are good.
