Not a worthwhile purchase you have to stay with the same flavor and can't change until you have finished the one you started its not the best at keeping the water anything but room temperature

The flavor is strong on 3 so I thought it would be a good choice but has that diet aftertaste that keeps me from drinking diet sodas. My Hugh complaint is this doesn’t keep water cold for even 1/2 hour. Was a giant failure for me.

Junk, cant get the proportion right. It's too week or too strong. It's not what it looks like, to pour in water and it mixes, it doesn't. water flows over flavored filter as it comes out.....not a good design. Good concept, not good design.

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 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!

I got the starter kit because I didn’t want to get tied into a subscription if I didn’t like it. I love it!!! I really can’t drink plain water and finally I can get flavored water with out the mess of adding drops or crystals (which half of it seems to go outside the bottle lol). All you do is insert a flavor cartridge and twist till you get as much or as little flavor as you want. I’m now pretty much just drinking water and have cut the 2000 or so calories from soda out of my diet and have lost over 35 lbs. I would totally recommend Cirkul.

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’m not much of a water drinker simply because of the chlorine taste. I love this bottle. With my water filter and pitcher and Cirkul, I drink three times as much water as I used to. Not all the flavors I’ve tried are my favorite, but I have the ones I’ll drink all the time and wow! Very good!!

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 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.
