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

This is a great tumbler. I like the 40oz size. It keeps ice for over a day. I love the straw so I don’t have to tip it to drink. It is very sturdy and stands alone just fine without falling. It’s not heavy even filled with water and ice. The cartridges fit fine just like in their lid.

Love it so much came back and bought two more, got the apricot one for $16 and l’m now drinking water like it’s going out of style, yay!! If you’re like me and you hate drinking water you need cirkul. The sips are great. They make water taste fantastic and these cups keep ice frozen for a very long time. I enjoy water more when it’s ice cold. Definitely try it if you’re like me.

Great tumbler, it's pretty and eye catching. Very cool product for traveling especially in most airports where they have water fountains where you can fill for free. Fyi the lemon aid isGot a very skunky taste. Yucky.

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.

Nice quality insulated tumbler! I love the color! Keeps beverages cold and like that I'm able to drink flavored water via the cartridges. Makes water less boring. I struggle to drink enough water daily, so having my water flavored is a huge help.

Great product. Large size allows for more ice to keep your drink cold while having more liquid to handle your thirst. Drinks stay cold a long time. Ice is still in the tumbler overnight.

Great concept, and the weight is nice and heavy for a mug. The flavor does fade off after a while even though there’s plenty left in the cartridge. And sucking on the drink to get barely any flavor is wild. But altogether it ain’t bad cause I like water. I want my flavor though. *3

Getting my daily water has become easier and more flavorful . After using the original Cirkul for a few years, it was time to upgrade to a container that matched my busy lifestyle. Added bonus, it’s sturdy and fits in the car cup holder!! Get this bottle
