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

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!

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!

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.

I really love this cup! It’s a great size, the color is perfect, and I was lucky to grab it on sale—fantastic deal. The only downside is how expensive the refill cartridges are. The cup itself is awesome, but the ongoing cost of refills is something to consider.

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.

We all liked these the quality was amazing, it was leak proof, the taste of the 6 pack tea was amazing from what I have put in now I have the peach tea and at a level 6 or 5 it’s perfect any higher it’s too much for what I think I would highly recommend

Got this instead of overpaying for a 20/22oz clear bottle package at the store. I got a color I like and it is 40 ounces!!! The handle is awesome and ice lasts all day. For anyone new to Cirkul the filters should last for about 2 whole fills with this!
