Nice change if you are looking to up your water intake. Great flavors, beware some have caffeine. Also, the refills are rather expensive purchased alone.

Nice water flavor system, lots of flavors to pick from, caffeine, vitamins, easy to use, makes drinking water easy when you dont like water. You can also make the flavors strong or weaker, by twisting the cap.

My kids and I love our Cirkul bottles. We are not fond of the teas, but that’s just our preference. We love most of the other flavors we have purchased. Wish they weren’t so expensive, but what isn’t nowadays. We would definitely recommend.

The starter kit is decently priced with 2 good flavors to get you started, wish they would have another option for hard shell, even if it meant an extra 5 or 10 more

Package arrived as planned and in good condition. The water bottle took a few minutes to figure it out but works well. We just installed a water softener and don't need bottles of water anymore so this product helps flavor in a different way.

This is great for those have a hardtime drinking water. Good flavors and the ability to make each drink at the level you like. Recommended to everyone 100%

We love our Circul bottles!!!!!! My daughter and I have never drank so much water in our lives! I know I feel so much better. More energy and my system is working better.

Great tasting and convenient to use, I also like the portability of it. The bottle fits nicely in my car cupholder slots so it's easy to take everywhere. The large openings, both for the cartridge and lid, make it easy to refill with water.

Bottle sweats excessively. Ice lasts about 30 minutes in the bottle. Even after adjusting the air flow valve, the water flow is very poor. It’s like trying to drink a thick milkshake. Flavors are ok at best.

I like the flavors but I hate that you have to suck so hard on the bottle, it's like drinking a frosty from Wendy's except it's the whole time and never thaws out!
