High quality bottle made of stainless steel. Lid and cartridges are made from a durable plastic type material. Excellent idea for someone who has difficulty drinking plain water. I have tripled my consumption of water using this method.

I really love this product!!! I was trying to stop drinking soda and finding this was the best thing i love the flavors and the variety they have and my grand daughter is always drinking my drink she loves it too :)

[This review was collected as part of a promotion.] Product is very good, quality is very good, the flavor cartridge is a little expensive for the amount it produces, overall satisfied

keeps drink cold, holds up well to my 3 year old who won't let me drink it for 2 seconds before she steals it for herself. I've also got my 13 year old convinced to drink water with all the flavors available

My daughter absolutely loves this water bottle. The only complaint I have is a cartridges do go fast they last her maybe a couple days if that, but she loves taste.

I literally drink more water because of this. There’s so many flavors to chose from and I am having fun trying them all. I am glad that I purchased the stainless steel version

I like the design but I wish it had a handle because it is a little large around the middle where you hold it. It is a little heavy but it keeps my drink cold so it needs to be heavy I guess.

It is way to big. I wanted something installed that I could take with me. It is so big it won't fit into cup holders and won't fit under my water filter on my fridge.

I converted my whole family to Cirkul and it’s the best decision I’ve ever made! We all prefer the stainless steel version because it hold ice better than the plastic.

I bought the stainless water bottle starter kit to get him off of soft-drinks and he loves it! It’s a great alternative to sugary drinks and helps increase his water intake…a win-win!!!
