I love my Cirkul! I am a teacher so I am constantly drinking water and the Cirkul makes it so much better. The stainless steel bottle keeps the water cold & the ice is often still in the bottle the next day. The flavors that I have tried have all been really good but my absolute favorite is fruit punch. The Cirkul is a great way to increase your water intake!

The product is not as advertised. On level 3 the flavor only last 2.5 refills of the 22oz cup not the six advertised. You will never get to six refills because level 1 has zero flavor and you lose flavor on level 3 when you finished refill number 2. I do not recommend if you are looking to save money on flavored water. Will cost you more to purchase the refills than any other drink that is premade.

I love this bottle. This idea is great. I bought the insulated bottle so I can have it near me all the time. I have found that I am turning the flavor off and just drinking plain water. So if you don't like water it worked for me. Thank you. My favorite so far is sweet tea…

First, the different flavors have different flow rates. The bottle is easy to use. I love that the flavor cartridge has its own mouthpiece, so when the flavor cartridge is changed, you get a new mouthpiece. So far, I love all the flavors. I have found that you start with a low setting and get a flavor, as the cartridge empties you have to turn up the level to get the same taste. I have the plastic one and the stainless steel. I use the plastic one at home and the stainless on road trips. I hope they develop a larger bottle. I am drinking more water than ever! Both the plastic and the stainless bottle fit into the drink cup holder in the car. I would like more flavors, please!

So, I’m a Cirkul fanatic. This is pretty much the only way I can get myself to drink the amount of water recommended in a day. However, I really had an issue with the Cirkul plastic bottles because they seem to get moldy super fast. While switching from being a full time soda drinker to a full time water drinker I did have to slowly remove the soda or I would get tremendous headaches. However, if I stopped drinking out a plastic bottle long enough to sun in a soda , by the time I would go back to that water (maybe 4 hrs tops) there was a bad taste. After putting the tumbler in the sink and coming back the next morning there were literally mold or mildew spots. The bottle washed up beautifully but that just doesn’t work for me. With the stainless steel bottle this issue doesn’t exist at all. I’m a real fan!

It is very heavy. I was surprised. I do not recommend the white. It gets dirty easily, no matter how careful you are. I would recommend getting a different color. Positive side is that is does keep the water cold and the inserts last longer than I expected.

Once I refilled the bottle for a third time, the cartridge had lost its flavor. I replaced with the second cartridge, and again no flavor after the second refill. I made sure to keep it dialed down to a lower setting, didn’t help. Great concept underwhelming execution.

It’s an awesome cup and all but what no one tells you and you have to do a Google search to find this out is how hard you have to suck to get water out of it also the flavors seem to be made with Splenda sugar and have that weird after taste that I’m not fond of other than that love the concept of the cup and my hats off to the creator amazing idea genius honestly

I love my stainless Cirkul bottle, it )the stainless) keeps water cold longer. I now only drink (Cirkul) water when I’m at home. I’ve cut out all soda during the week. It doesn’t even seem like I’m drinking water, the flavors are great. I’m totally hooked.

I had to return first one for the cap malfunctioning and the same problem with the second one im so upset i just use my old cap that was on my plastic jar fits fine no leaking and or nothing coming out at all like first 2 stainless steel bottle caps i purchased pathetic
