Cirkul40oz. Chameleon Stainless Steel Tumbler with Handle, All-Day StrawSip, Double-Wall Insulated

I ordered this cup because my daughter and I were too excited to try Cirkul and didn’t want to wait until our order was delivered to start trying these guys out. The cup was very nicely priced and I purchased flavors from Walmart. I will say there may be some kind of bug in the design as sometimes the flavor doesn’t come through, only water even if the flavoring is set to 7,8,9 etc. however for me, I like that because I really do love drinking water wether plain or lightly flavored or heavily flavored. It’s got my kiddo drinking SO MUCH water. Which is great because she never ever drinks enough. I can’t wait for her 22oz bottle to arrive so she can take it with her to school and etc. this is an awesome addition to my plenty plenty of cups.

The color’s even better in person. Got it for my 7-year-old—it’s basically half his size, but we added a lanyard and now he’s living his best hydrated life. Made of stainless steel, so it keeps drinks super cold and could hypothetically be used for self-defense on a lanyard😅… totally joking! (Kind of.)

I just got this yesterday and am super happy with it! I did find I wasn’t getting the flavor at first but tipping the bottle upside down a few times brings the flavor through. It keeps my drink cold, doesn’t leak. One thing I would like is a place to hold the attached cap down.

This cup is freaking awesome! My fiance has been having trouble with his water intake but this cup takes the cake! It's easy to clean and use. Would totally recommend on buying this!

So far so good. I do keep trying to tip the tumbler to drink from it like you do with the original Cirkul bottles. It is nice that you don't need to do that with this one. It is somewhat heavy, but 40 oz of water will do that somewhat (40oz of water is 2.5 pounds).I like the fact that I can use this and not need to refill constantly while I sip. I tend to go really light on the flavors and with the old one I would refill the water bottle around 4 times. Not a big issues when I'm at home, but when I'm out and about it is nice to have more water with me. Seems to keep the water cold for a decent amount of time as well. We'll see if that keeps up when summer happens!I wish I could buy a spare lid that I could use with just a regular straw for days that I want to just drink plain water. I haven't attempted other replacement lids to see if any of them would fit, but I do plan on trying that.

I've been a Cirkul user for a couple of years (maybe 3) and decided to get the tumbler due to hearing great things. I use ice from a tumbler ice mold, which lasts hours longer than in any other Cirkul product. I have the 20 oz plastic, 40 oz plastic, 32 oz steel, and 40 oz steel, and the Cirkul tumbler keeps the ice longer than any of those. The only problem is the same as many users, I have to put the sip to 10 to get flavor. I did remove a seal, which has helped, but I still have to increase to 10 after a couple of refills, which is not typical for the sips. I alternate when I can't taste anything and place a new sip into the tumbler and take the tumbler sip and place it into one of my old bottles. The sip is still good for a few more refills. I gave it a 3 and hope Cirkul fixes the issues with the straws, but I don't recommend.

I am so happy I ordered this! I use it every day, carrying around with me all day. It’s always right beside me and I’ve definitely increased my water intake.

LOVE THE COLOR. THE TUMBLER HOWEVER, DOESN'T KEEP DRINKS AS COLD AS OTHER TUMBLERS DO. I KNOW THAT ISN'T WHAT IT'S FOR AND IT'S MORE ABOUT THE FACT THAT THE LID WILL HOUSE THE CARTRIDGES...BUT IT WOULD BE NICE IF THE TUMBLER ACTUALLY KEPT MY ICE COLD. MY ICE MELTS RATHER QUICKLY! I KNOW THAT THIS IS MORE OF A CIRKUL CARTRIDGE ISSUE...BUT I HAVE NOTICED THAT THE CARTRIDGES ARE HARD TO DRINK FROM. THE SUCTION ISN'T GREAT AND THEY DON'T LAST VERY LONG. I WILL NEED TO USE IT A BIT LONGER TO SEE IF I WILL CONTINUE USING IT OR GO BACK TO MY MEOKI TUMBLER AND FLAVOR PACKETS.
