At best 2.5 fills even on low number where you can barely taste the flavor. Great concept but does not deliver.

its very inconsistent in the flavor being added even though the cartridge is full. it isnt worth the money at all

I love the insulated white bottle-stays cold all day with very little ice ! Like the fruit punch flavor and look forward to trying other flavors!

I love it and I drank a lot of water more than before because I liked the flavor in my water bottle. It helps a lot

the flavors are fine but the fact that even the metal bottle do not hold the cold it is completely useless

Great option for on the go hydration. We actually did the math and it’s not much more expensive than powder mixes.

nothing but problems using this 22oz water bottle. Searched Google for hacks to get it to work. product is garbage. returned for full refund.

they left it at my mail box and they are dogs around here......it is not there......so upset about this!!!!!

works great, keeps liquid cold for long time. love that you can adjust the flavor to taste. only wish was that it held more liquid.

I like it. It doesn't keep drinks as cold as my other insalated bottles do. But its good . I really like the strawberry lemonade one
