The idea is a good one - have cartridges of flavor you easily sip through to change up the taste of your water. But the implementation of the idea didn't work for me, and I returned it. The dial that alters intensity of flavor almost immediately kept producing high intensity flavor even when set at low numbers.

The flavor cap is super potent at first even when dialed back and causes it to quickly dissipate to nothing withing the first 50 to 75% of a fill up. This affected 4/6 of the cartridges so far and have two unused, but because of the the potency at first the other 2 are unused due to the quality control issues and the very potent sour flavor. It's an really expensive water bottle. Do yourself a favor and just pick up a case of water and a few boxes of flavor packets or just get a standard water bottle.

Cool product in theory poor execution. Does not work well with iced water. The ice will make the flavor inconsistent sometimes needing to be adjusted up or down. I have not been able to put on one setting and enjoy the same flavor amount. Sadly this product is not worth it.

Good alternative to practically any other drink besides plain water, yet I'm not quite sure how I feel about regularly consuming the artificial sweetners used in every flavor... The plastic bottle, lid and flavor cartridges are all of good quality. Flavor delivery can be inconsistent if the lid, or cartridges are screwed on to tightly, and too much pressure builds up inside the bottle.

Tastes strongly of chemicals and is unpalatable.

System doesn't work, negative pressure causes problems

Too hard to drink, and if you make it easier it spills.

Bottle leaks from the spout.

This is amazing and I will be drinking more water now

Flavor only last for one bottle and can’t hardly get any water to come out until less you pull the port out
