I love the idea but upon initial use it is too hard to drink from. You have to suck pretty hard just to get any water out and then I'm still barely getting any water. I have the flavor set at 2 because when i tried to go higher i was sticking straight flavor and no water. I have 3 other flavor cartridges so I'll continue trying with the hope it gets better but if they are all like this i won't be using it again.

i would never purchase again. every time you take a drink frim the bottle you must release the pressure before you can get another drink. literally SUCKS

I love it! The stainless steel bottle is the way to go if you like it to stay cold I put I few ice cubes in and it’s perfect all day. I loved the Grape and waiting impatiently for my new order of many more flavors!

I am not a water drinker unfortunately and one of my co-workers had a Cirkul water bottle and I tried it and fell in love instantly. I have never been so hydrated in my life I love the flavors and the bottle itself. So worth it!

I love that you can choose how much flavor you get in each swallow %26 that you can change it easily to just plain water. It also keeps your water cold for a pretty long time.

I like the flavors but you have to put the flavor setting low to have the cartridge last the 6 uses. Otherwise a great purchase if you’re trying to intake more water.

I bought the stainless steel bottle thinking my cold water could last for awhile but it turns out the bottle fails to keep my ice cold water chilled for even 10 mins.

Just got mine today so far so goood. Its a great idea for drinkin more water. The sips come in great flavors plus if u look sum like the blue raspberry is for energy cant wait to c if they work. Fast shipping.

I love the stainless steel bottle. It keeps my drink much colder than the plastic one. Very affordable. I looked at other stores ie, AmZon, and Wal-Mart was the best savings.

Keeps water cold for a good while. Better than the plastic bottles. I bought another one for my daughter (but she’s going to have to get her own sips!
