Cirkul 24oz Slate On-The-Go StrawSip Tumbler, 1 Flavor Cartridge (LifeSip Passion Orange Guava)

I have SOO many big water bottles, this is absolutely perfect for me!! I can use this on short trips and fill up my larger one when I'm taking longer trips. It keep its cold for quite some time, but I do add some ice, even though it says to watch how much you put in. But over all 5stars absolutely!!

It's really nice to be able to sip from a straw like cup. The only thing is that I like to use Topo Chico carbonated water to get a soda like drink but the pressure from the carbonation makes the water spew out, so I use only regular water and use the carbonated water in my other bottle that you tip to drink.

I love Cirkul brand cups and flavors. This cup is too cute in the purple color. I love that it is stainless steel so it keeps drinks cold. I would absolutely buy this again. It was on a great sale and it came with a flavor cartridge that tasted good. It is a great value. I love it. The only two things I might change would be for it to hold more liquid (I think this is either 16 or 20 oz and I drink a ton of water in a day) and for it to have a handle, that would make it a bit easier to carry if you have your hands full. Other than that, it is a great cup, I adore it and use it all the time.

LOVE these cups, i have 3 now in my house between my husband, son and myself! they're super cute and they encourage you to down a lot of water! theres definitely a straw suction thing that happens sometimes where it doesn't really want to give water, and then another irritant is the need for a low ice level/ mostly full cup or it dies kind of impact the flow. However, ive never found something else so nice and convenient, really genuinely appreciate the adaptability and concept.

There are so many tumblers out there. Something for everyone. I keep this one near my bed so I can take my meds through the evening. It took me a bit to get used to not tipping it to drink from but once you get it right it's perfect! I love the color and the design.

You have to sip it extremely hard for the flavor to come through at all, then just water for a bit until it wants to come through again. I thought it was my cartridge but I tried 2 other ones I had and still would just be 100% water.. I bought this bc I loved my plastic bottle so much %26 figured this would be a nice upgrade, now I almost regret but love the color so much. I'll just have to figure out how to use it with out the cartridge or just no lid I guess. 💁‍♀️

Don't buy this. Trust me. Don't. I joined all the Facebook groups, Reddit feeds, YouTube videos, FAQ. Can't get the thing to suck water up the straw. Every time we tried, mouthful of flavoring like fluoride tasting. Seriously, I did it all. Remove this, add this, twist this, open this, cut this, loosen this. Nothing worked.

I bought 9 of these 7 for gifts ALL 9 ARE DEFECTIVE! I kept 2 neither would work! I opened up the rest of them NONE OF THEM WILL PULL WATER OR FLAVOR THROUGH THE STRAW! I've spent all day with Cirkul to try to get them working to no avail. DO NOT ORDER! Big disappointment!

cannot taste the flavor cartridge, tried adjusting from 0-9. . . i only got a small taste of the flavor only when at 9. love the actual cup and how the straw works, but really wish the flavor would come through. pretty mad i paid how much i did for it, and it was on sale. i got one for me and my boyfriend... should've just stuck with the original bottle.

I ordered this cup for my husband for Christmas. I ordered this one specifically because it came with a flavor cartridge. I got it delivered from the store and it was supposed to be there between 11-1. 11:30 rolls around and Walmart tells me my order was being returned to the store even though I had it set to leave at my door no one had knocked on my door at all. I reordered it for 3-5 and was outside when the order came I took it inside and noticed it didn't have the flavor cartridge and didn't come in a box. I looked at my order to see if it had been substituted for a different cup it had not. So I guess this is all to say if you want this specific cup go get it yourself because this was way too much hassle
