It was a birthday present for my grandson! He lives it and is drinking more water now because of it! It is made very well, im pleased with it and i bought two others for his brothers! The flavors are wonderful that you can choose from and he says it tastes great!!!

Well my philosophy is don’t ask unless u want the truth!! It’s basically like drinking watered down koolaid-which I always got the shakes real bad from it so wasn’t something I could drink so …I gave a 4 star cos the thought process was good…also I bought up n got the aluminum cup and was very disappointed because it didn’t keep it cold and in my opinion it’s too heavy for exercising n staying hydrated….sorry but I’ll just keep my Dasani water!

my grandson he loves it, I bought it for him i have never tryed it it comes with the bottle and the filter that go in the water that in the bottle it mixes to flavor the water as strong or weak as you like it he use to drink it a lot but he has has decovered root beer now but he still grabs it when we or own the go

This was a gift, the person I got it for loves it. They said they were able to give up soda after getting this. Also something I did not know and others looking at this might not be aware of, you can control how much flavour it has so you can go from just a hint to full flavour. Best $30 I have spent on a gift. My only fall back is the cartridge’s, they appear to be disposable. I would really like to see some sort of return to be reused option. Other then that fantastic and very satisfied.

This is brilliant, amazing and still saves money! I love the bottle and the fact you can change the collar colors! I love the taste of all the flavors cartridges, especially sweet tea! Yummy! The cost is amazing and I’m totally hooked! What a great and tasty way to get your water in !

Attached filters are difficult to suck water out of bottle and drink does not stay cold . This is not a hydro flask. Overall design of bottle is ergonomically correct just doesn’t keep your water cold . This is why my rating is low and the suction while drinking is difficult. Return doesn’t meet expectations

definitely don't sit on this I work from home person very busy I literally don't drink water at all but this thing right here you don't even realize how much water you're drinking I feel this bottle at least six times in 8 hours so good for getting your water in that's just in my 8 hours of work one cartridge will probably last you 5 days highly recommend

It’s an awesome cup and all but what no one tells you and you have to do a Google search to find this out is how hard you have to suck to get water out of it also the flavors seem to be made with Splenda sugar and have that weird after taste that I’m not fond of other than that love the concept of the cup and my hats off to the creator amazing idea genius honestly

I really like that the Cirkul stainless steel keeps the water cold. I love the flavors. The only problem that the flavor cartridge has to be changed every few days. That can get expensive. But everyone probably won’t have the problem. I just drink a lot of flavored water.

This is the best product for a lot of reasons but here are just a few. It's worth the money due to the fact that refill cartridges are cheap but good flavors. Helps reduce the use of plastic bottles. You can recycle the cartridges that you use for free at no charge to you. Depends on how much flavor you want but 1 cartridge can last you 1 month on the setting of 2 or 3. I love it, plus I add real fruit to mine. I recommend getting this product!!
