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

The cup is great! Well built and keeps ice in it all day even with multiple refills.The Cirkul pods though, I am not impressed. Flavor runs out way too fast for what you pay for them. Maybe there is an adapter or regular lid I can get and will just use this as a regular cup from now on....

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.

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.

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.

This water bottle works pretty good! It is a little heavy, but it is sturdy. It is hard to get water through the flavor cartridge. The taste of the Cirkul flavorings are always good, but that doesn't affect this cup.

The tumbler does keep water and ice for about 18 hours. The straw works great. But I bought the tumbler for the flavor. Very difficult to get any flavor. 75% chance of flavor if I tilt the tumbler two or three times then drink.

I love how it looks, its insulated, leakproof, it has a smaller base then most 40 oz cups so it fits in a lot of cup holders

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.
