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.

Not bad, but had issues with air flow. The small stopper fell out almost immediately into the water reservoir. Now the water leaks out the air intake.

Bottle didn't work very well, the rubber gasket needed to be altered in order to drink properly. There was no air being let in. So I had to poke a hole in it or open the lid after each drink. Now it's very loud and you have to really work at sucking the liquid through the mouthpiece. Not very happy with this purchase.

For some reason the bottle builds up a lot of pressure and makes it impossible to get the drink out. I have had a Cirkul before purchased from the actual website and did not have this problem.

This review is product related and has nothing to do with Sams Club. Most of the flavors left a horrible taste in your mouth regardless of what level i put the cylinder on. Then their is the design of the tip to suck from. There is no sip, an obnoxious sucking sound. Horrible design. I will continue to buy packets if i want a flavored water.

I had a friend or two that said they really enjoyed this and I finally had saw it in person but even on the lowest setting for flavor it still tastes really strong like someone dumped the powder in your mouth and a sour head. Oh well. Maybe I got an off one :(

I wanted to love this. Unfortunately, the cartridges did not want to release the flavor as they should. I was constantly trying to trouble shoot why the flavoring wasn’t flavoring. You also had to sip so forcefully that the bottle would make chugging water sounds and you would have to unscrew the top to release the pressure.

I personally didn't enjoy it because I kept having to open it due to sucking on it and it stopping the flow of watee.

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.

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.
