Great product especially for people who may not like to drink plan water, but unfortunately it seems that the cartridges do not last for 6 refills and that's when I'm using no.4 setting

This is how I got started. Now I have the stainless steel bottles and I’ve bought bottles for every one of my grandchildren. They never drank water before now I can’t keep their bottles full!

Great concept for drinking more water. The flavors are a nice addition to the water. With that being said if you like your water to stay cold or even cool this does not do it.

Flavors are good however when trying to suck out the water, you suck out all the air and then nothing comes through. Frequently have to burp the bottle for this reason I would never buy anymore.

This product is just okay. Very hard to get started. The flavors are very strong at first. Once everything gets going properly its good,However the cartridge runs out quickly.

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

Hard to suck the water through it, if you want a different flavor you have to take the mouth piece out and store it somewhere, all the while it's growing bacteria till you want that flavor again.

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.

I’m a postal worker that needs to drink lots of water. With cirkul, I hit my water goals!! Love the different flavors and the option of caffeine or no caffeine!!! Keep up the great work!!

Love the flavors and the bottle.. I got my first bottle and I loved it my daughter took it away from me so I bought the metallic ones and I'm so in love with them I carry it to work everyday... excellent for on the go no spillage.
