The Cirkul Water bottle was made in 2018 but became popular around 2021 to 2022. The Cirkul water bottle allows users to flavor their water sip by sip. The user is able to choose how strong they want their designated flavor to be and they are able to change it back to no flavor when finished.

How to use the Cirkul water bottle:

• Fill your water bottle up with water
• Insert your flavor cartridge into the lid and fasten it by turning clockwise.
• Turn the dial to adjust flavor strength. 
• Tip the bottle up to sip and enjoy!

The cost of the Crikul water bottle ranges from $12 to $35 depending on size. The flavor cartridges are $3.75, or you can bundle up to save.

I chose the Air up water bottle to compare to the Cirkul Water bottle because both bottles allow you to choose your flavor. There is quite a bit of difference though, like the price. For an average 22 oz Crikul bottle with 2 flavor cartridges is $19.98 at Walmart (or online) while a 22 oz Air Up water bottle with 3 flavor rings is $44.98. Overall, the Cirkul water bottle is easier to use and much better priced. Crikul water bottles are available in stores and online, while Air Up bottles are only available online.

I recommend the Cirkul water bottle to others because this product has helped me drink more water and less soda, the flavor contains no sugar, no calories. The cartridges have numbers on them where you can choose how much flavor you want  in  your water. Instead of  water packets, which you must constantly add to your water whenever you run out. A Cirkul water bottle only requires that you replace it with water, and the cartridges can last for at least 4 to 7 days ( or longer depending on the setting of flavor).

I would rate this product a 5/5 because it is overall a great product and would be helpful for everyone.
