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.

I bought one for myself back in October of last year and then gave four of these as Christmas gifts. I've been so much better about drinking water since it tastes so good, and that's a very good thing. There's such a variety of flavor of cartridges available online, you're sure to find something you like. My favorites are the tea-flavored cartridges. The only negative I have is the cartridges only last for about four bottles of water for me, and I usually have them at 3 or 4 until they start using flavor.

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.

I was a little skeptical at first because I already drink a lot of water, but I needed my children to drink water and I always heard the saying "Mom it has no flavor!!" I got frustrated and almost gave up! I was on TikTok and the ad for this product come on someone's page so I said ok I'll give it a try. I wasn't disappointed at all in fact it's the best thing that has come around!! My children love it! Thank you so much to you all for the most awesome hydration for my family and also they don't really want to drink sodas that much!! I work in a warehouse and this is what I drink so I don't have to taste the chlorine in the water at work so I stay hydrated! I also get my coworkers asking about this and I always tell them how good it is and tell them I'll give them my link given to me so they can order! Yummy water flavor awesome way to stay hydrated.

I love my Cirkul and water bottles and flavors. I used to drink at least a 12 ok or diet soda every week and now I only drink from my Cirkul bottles. I have 2 so I always have a backup. There are so many flavors and they are coming out with new ones all the time. The customer service is also great. I have purple ones as that is my favorite color. It’s cool that you can customize them like this too!

Doesn’t keep your water cold or cool. Would rather buy the insulated tumbler adapter than use this bottle. The cartridge is a little noisy, needs better airflow, IMO. I do like the flavor cartridges and the wide variety of flavors to choose from. I keep mine dialed around 3-4 and it will last for 3 -4 fills. It definitely has me drinking more water now.

I love the idea behind this. I have bought both the insulated and the plastic water bottle. Both bottles are great. The cartridges so far have all had great flavor but the issue is they dont last as long as they say. I usually keep the dail at 3-4 depends on the flavor and the cartridges will only last me at best a day and half.

I have had a Cirkul for a while now and I have to say they exceeded my expectations on flavor and the quality of the cup. I have only found a couple flavors that I do not really like, but I know I would like all the flavors, I can be a little picky. I have since got my husband a cup and got my kids the lids to fit on their Contigo bottles (from Walmart). They absolutely love the sips and enjoy trying new flavors. I wish the shipping was quicker but overall my family loves the products.

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 this...but decided to try it by borrowing one from a friend to see how it would work for me. The flavor cartridge...even though I had it turned to between 0-1 only lasted me 3/4 of one day...maybe 6 bottles. I thought it would last longer because I had the flavor so light...but no. Replacement cartridges are like $4 each at Walmart (best place I could find). So I decided this was not cost effective for me and returned my un-opened purchase.
