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

I jumped on the big cup trend a little late but I LOVE this cup. I have been using it so much that I have basically cut put all sodas which has been a challenge in the past for me. I feel like the flavor cartridges last longer using the cup then when using the bottle (my husband has the bottle amd has gone through more cartridges than I have even though he has it set on a 3).It keeps my drinks cold..The only complaint i have is it can take a lot of suction to get the water up through the straw.

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.

Yes, it was hard to sip out of it for the first week as the silicone parts broke in and loosened up, but after that it was perfect. I washed the parts with hot-ish water every day (not boiling hot) and it loosened up over time. I fill it up in the morning with chilled water out the fridge and it stays cool all day, I don't even need ice! The chameleon color is beautiful and I feel so proud holding and carrying my giant water container around the house. My husband is happy too, since I was always so bad with water intake. But not anymore!

So far so good only my first cartridge that I opened brand new and inserted into the tumbler didn’t work and yet it did work in my thermos so that’s pretty frustrating ! I do like the tumbler as it’s very pretty first of all and let me just say the ice lasted over 24 hours without melting so it keeps the water very cold which I really like. All in all this was a great price and I like the amount of water that it acually holds in comparison to the thermos that I first bought. I really am glad I got it and hoping that I don’t have any further trouble with the cartridges.

Use it everyday! It's got a great seal, I think one thing to consider is that you will want a strap to carry it if you travel or are a student. Easy to clean, dropped it (on accident) a couple of times and just have a minor dent in it. I have not ran it though the dishwasher though... and don't plan to just because I have had other water bottles similar that have had paint peel off. Completely worth the money for someone who also hates getting water all the time!

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.

I bought the smaller size to try it out. And now 3i'm buying the bigger side size, so I can big moir, without refilling. I love that I get the flavor I need.Without having to stop and put more flavoring in this stays with all the flavor for 3 bottles

Great product! However, one cup had a dent in it from the delivery, but I don’t have time to return it and get a new one because I am going out of town with it
