Cirkul 40oz. Carbon Stainless Steel Tumbler with Handle, All-Day StrawSip™, Double-Wall Insulated

This is my second Circular tumbler. I appreciate the modern design and choice of colors. I can pour cold filtered water in, add some ice, and sip all day without adding more ice. Keeps the water cold! The flavors are excellent, with a few exceptions. The lemon has no flavor, no matter how high you dial it. Then there are a few too sweet for my taste. Favorites are the Honey Crisp apple and the Passion Fruit/Dragonfruit.

Super happy with this cup!! Tried to buy it locally at 2 different stores, neither had it in stock. The lid can be fit for left or right hand, keeps ice for a long time and works like it should!! Absolutely recommend. Looks amazing too, as it matches my watch, earrings and uniform at work!! What more could I ask for!!!

Cirkul stands behind their products, even on Amazon! There was a small dent in my cup and they gave me the option how to make it right. I love my Cirkul sip cup! I've been a fan of the other styles of Cirkul cups as well for a few years!

I really loved this water bottle, very stable, very durable, sometimes I have had struggles with finding a good grip for the removing the lid, and it occasionally pressurizes on the inside so when you go to take a sip, its loud and the intake makes noise, other than that I do highly recommend! Its very large, does not leak, easy to clean as well! If your looking to keep your bevvys cold all day, I'd say it does a fairly well job, 14+ hours of ice retention. Good for all day use!

I love it! I use it everyday and take it everywhere with me. It was a little bit of an adjustment going from the regular sip Cirkul bottle to this straw sip but now that I got used to it it works great and keeps my water cooler longer. I say cooler because the one downside with these Cirkul cartridges in general is that ice and/or being too cold or frozen makes the flavor not work very well for whatever reason however once it gets warmer again the flavor comes back. Overall I love the flavors and it has really helped me stay off of any sodas or other sugary beverages.

I chose the Cherry Blossom thinking it would have the actual blossoms on the bottle. Of course it did not but the color is very pretty, very light pink with a darker part on the handle. The first use with the cartridges was hard to get the water through the straw. You have to sip very hard to get the air out and the water started. Choosing the settings for the cartridges was trial and error. The first cartridge lasted longer but the second one didn't work . I do like this idea to get more water in on a daily basis. One reviewer suggested that the straw assembly may loosen up with use. I hope it does. The bottle is very durable and value for money is good . There was not any clear instructions for use even online. I would give more stars if it was easier to use.

Its not a STANLEY but it serves the same purpose. I don't like drinking plain water and this is perfect. The lid doesn't let anything drip out if it rolls over. Size is great 40 oz so 2 reg water bottles. If you fill it 3 times you went through one cartridge. I don't like fake or overly processed flavors. so its nice getting just enough and being able to control the amount of flavoring i get. I'm happy with the cartridges for now. I haven't been disappointed yet. I've been drinking considerably more water because of this bottle. Its built really well, so not disappointed. Its hit or miss on the ice retention. you have you balance out ice to water. The bottle actually keeps stuff pretty cool. I'm definitely OK with that. it does fit in most if not all the cup holders i have had to deal with.

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
