Recommended by a friend. Great idea, but…. Initially mine would only dispense flavor and no water. Disgusting! Searched and searched for what I was doing wrong. Eventually called their customer service who told me sometimes on new ones there’s a little valve under the cap (small, clear looks like a grommet) that is stuck closed. I wiggled it a little bit and then it worked, but I still find I have to drink with the bottle upside down which is awkward. Also the water doesn’t stay cold at all. Zero insulating capability. All in all a bit of a disappointment and after about 10 mouthfuls of concentrated flavor I have minor trauma from it lol.

I love Cirkul bottles. It has helped me so much with trying to quit drinking soda. My cartridges usually last quite awhile and they’re so yummy. The only problem I have had is near the end of the cartridge I can’t taste the flavor much and it’s turned all the way to 10. And I can see there’s still flavor left in the cartridges. But other than that I have loved my Cirkul bottles. I’ve got all 3 of my daughters hooked on them as well.

I love using cirkul water bottle! Has so many flavors. It is a great way to stay hydrated especially if you don't like drinking regular plain water. I love how it has 0 sugars. My bf has tried out the flavors and he loves it too, so i bought him his own bottle. I do 8 cartridge subscription plan every month. Definitely worth the money to invest in it!

Taste is great for sugar free however the bottle has a strong suction between the opening and the flavor cartridge that you insert. When the cartridge is even the slighest bit screwed in too tight, the suction prevents liquid from coming out and you can't get any drink. You have to unscrew it a little each time you want to take a sip.

I bought this for my grandson as an Easter gift. With a gift card he was surprised and loved it.cirkul flavored water cup is a good buy and at a great price. He was surprised these are great gifts for kids and adults I would purchase again and again thanks to Sam’s Club.

I absolutely love the idea cause without the flavor cartridge's I wouldn't want to drink more water then I ever had. However, I have the hardest time opening the cap on the cartridge when 1st opening it from it's packaging. There have been sometimes when there still is a film on the cartridge mouth piece causing me to use a small flat head screw driver to open up the mouth piece so I can enjoy the flavoring.

I like that there’s so many different flavors and I drink so much water now than I did before. One flavor cartridge depending on flavor for me does last about 6 refills sometimes more. Example I love the lemonade but I like it on the in between 3 and 4 so it might be 5 refills. I took with me to Disney trip put the Sweet Tea, then just filled up with water at the parks.

Love all of the different flavors available. My only two real issues with the bottle is the fact that it sweats profusely (I bought an insulated one to put my top on) and the spout will continue to leak after taking a drink. Otherwise, I have no complaints. I drink pretty much from my bottle all day, every day and it has greatly improved my water intake.

Absolutely love my Cirkul! I drink more water now then I did 1 year ago. I feel healthier and many friends and family have noticed. So many awesome flavors! The only thing I wish I could change is the cap. Not fond of the cap but that is just the only, only negative thing about it. Everything else is awesome!

I bought two of these, one for each kid. The boys were very excited since these are a cool thing at their school right now. However one broke almost immediately. Also a few of the flavors are caffeinated which I don’t love ( not for kids, I bet it’s great for adults that want it). The other one is still working fine about a month in. The boys like the flavors.
