While the flavors are nice and the option to set the amount of flavor is great, they are just not large enough. I drink a gallon of water a day and found myself finishing this too quick. Also, they lack in keeping your water cold.

I never usually drink water, because it has no flavor. so when i saw this on tiktok, i had to try it. its really good and even better then the flavor packets or squeeze flavors.

Bought this for my 15 year old who never drinks water and he LOVES it! He’s been so happy and literally chugs water from it. I will say I think the coolest feature is that you can make it more or less flavorful. I like the options in cartridges too.

I have never been a very strong water drinker and that has changed with Cirkul. What blow my mind was flavors I've tried before and hated I suddenly loved. Black Cherry, Fruit Punch, Mixed Berries are some of my favorites to drink now.

Cirkul Flavored Water Bottle tastes fine. No instructions pm how to adjust the flavor flow, but I managed to find out. Thr lower the number used the longer the refill lasts. Refills are too pricy.

I have never liked drinking water until I got these cartridges. So easy to change out and a wonderful variety of flavors. It was definitely a life saver at work this summer as I work in a warehouse with no ac.

Please don't ever stop selling these at Sam's club, in fact, Sam's club needs bulk cartridges, or any cartridges. I tried this bottle because it was so cheap! I'm addicted now. I drink 7-8 20 oz bottles of water a day now with these. Amazing!!!

I never liked drinking water before the flavors you add yuk But the flavors cirkul has are very refreshing the fruit punch is my fav but i like several others and i fill my bottle 3 times a day now i really needed to get away from pop thanks Cirkul

Wouldn't buy again. Too hard to figure out. If you dont screw in the flavor thing just right, it just tastes bitter. I like the concept just not the actual product. I would've but it and if i could return it, i would.

Amazing continuous flavors I enjoy drinking water now. Never liked the powder flavors bc everything tasted so pasty. But with cirkul it’s made water drinking so much easier. Thanks cirkul for changing my options to a healthier life style
