Cirkul40oz. Midnight Blue Stainless Steel Tumbler with Handle, All-Day StrawSip™, Double-Wall Insulated

I LOVE this tumbler. I was never much of a tumbler person but I saw these and figured I would give it a try. I require less trips to the water fountain with the tumbler versus the Cirkul bottle which is good for taking it to work. I took the tumbler for a 8 hour shift and filled it with ice and water and when I got home, it was still cold and full of ice. It's never leaked on me even with the cartridge uncapped. My cartridges seem to last for 1 ½ to 2 full fills on the 6 setting. It's really easy to clean and isn't too heavy to carry around when full. Despite seeming like a straw function may not work effectively for a Cirkul cartridge I have no problem with it at all. The color Cherry Blossom is a very light pink, almost white, but very pretty nonetheless. I like that it has grip on the handle, and the bottom allowing it to not slip around on any surface. Definitely recommend if you like Cirkul and tumblers.

Great option for flavored water without wasting a bunch of plastic. I am terrible at drinking water throughout the day unless it's flavored. I got hooked on the Hint waters a while back but always felt kinda bad going through SO many plastic bottles. My sister introduced me to Cirkul and it's great! So far, the cartridges seem to last about a week for me and have plenty of flavor. This cup is very functional. It keeps ice water for 12+ hours.

Omg I love this it’s cheaper then Stanley and better quality and leak proof also easy to use just pick what flavor u want add water and sip away. The only thing I don’t really like that the taste goes away fast. But it’s better then drinking other bad stuff

I love the Cirkul products. I prefer this tumbler over the water bottles you have to tilt- they’re noisier. The only downside is the straw doesn’t suck up the water immediately, you have to sip air two or three times to get the liquid to come up the straw.

I love the Cirkul tumbler. It keeps my beverage cold as well as my Stanley tumbler. Cirkul flavor pods are so convenient and are available in all my favorite flavors. It a breeze to clean, it’s almost indestructible, seals very tight. Great value for the money!

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 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.

We absolutely loved these bottles. The filters work and make it easy to use. They clean easily, it does not taste like metal, and they are a perfect price for the quality that they are. Went back and got two more after this one.
