Cirkul40oz. Cherry Blossom 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.

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 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.

The mug is is very sturdy. I am definitely drinking more water. The sweetener they use in flavor cartridge is not tasty at all. I am disappointed about that. I wish they sold a cartridge that you could add you own flavor to.

Love my 40 ounce container. Love the flavors that I purchased with it . Was using a water container but always taste plastic when I took a drink . Very happy that it keeps my water cold and that I can change the flavor any time. Very nice color blue too.

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.

Well, it works pretty well, there is some plastic paste, from the flavor cartridge,. Particularly when you have the flavor cranked down to try and make the flavor last as long as possible. I keep on tilting the bottle up in order to drink from it, which doesn’t work well when you have a straw in there trying to get the water out of the bottom. I wonder if you can take that out. But it is a nicely made bottle. The flavor cartridges control is very sensitive, a small movement can make a big difference in the amount of flavor you get.

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.
