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

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.

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.

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.

Love the fact that I can finally drink my water in a cirkul tumbler! I love the way my ice stays for over 24 hours! It’s easy to take back and forth to work. Nice price for the quality of the tumbler. It’s easy to clean and it has stood the test of being dropped by my kids! The tumbler hadn’t dented or cracked, which really appreciate!

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.

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!!!

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!
