Love it

I really like the idea of this product. Just fill the cup with water, but drink a flavored drink. It's so fast and easy. The flavors are good. My favorite was the dragonfruit refresher. However, I'm having issues now with the amount of flavoring I get, even when adjusting the flavor dial, sometimes it's too much other times, it's barely any flavor. The straw part is also hard to drink out of and requires a bit of suction, and it's pretty noisy when drinking. It makes lots of high pitched squeaks and squeals. I don't think I'll want to continue using this after I finish this last flavor pack.

Picked this up from the local warehouse. I was hoping it would help me drink less soda and more water. Worked decent on the first of the 4 carts it included, but now by the 3rd, I'm having a difficult time getting any flavor to come through at any dial setting. Found numerous discussions online of this new Sip Straw design just not working well. I thought that maybe I had the dial turned up too much for the flavoring and I used it all up, so I dismantled the last cart I used that I was no longer getting flavor out of and gave the foil pack a squeeze while sipping from the mouthpiece. All flavoring. There is definitely something not quite right with these new designs of the Cirkul tumblers so I guess, buyer beware.

poor water flow and a loud gurgling noise, and we only taste the flavor by itself without any water going through

Would be better if it was not so hard to drink from.
