I can't drink plain water all the time

Purchased because I need to drink a lot of water after a recent surgery and I only have to refill twice. I love the size of it and the flavors that come with it. It really does encourage you to drink more. Would highly recommend and you don't always have to have flavors in it you can drink plain water also.

It's a great cup

Besides it having so many options for great flavors, and the dial on top to adjust how much you get. it's just an awesome cup all the way around! easy cleaning and the straw is awesome! Keeps cold all day!

Beautiful Cups

I purchased these cups as gifts. The colors were amazing. Everyone loved their gift. The only downside is you can't use it without the flavor spout.

Drink your water

I don't go anywhere without my 40 oz. Tumbler. This is the second one I've bought. This way I can wash one and use the other.

Makes Me Drink More Water

I like that this is 40 ounces. Cirkul advertises that you'll drink more water using their product and it's true, but... I feel the flavor pods cause you to become thirsty. I don't know what ingredients are in those pods to give me that reaction. Not happy about that. The other thing is that once you're done with the pods, you'll need to cover the hole where it goes. There is no cap to cover the hole! I had to buy screw on caps from an outside source. I'm not planning on buying the expensive pods at the Cirkul website, so the cap was a necessary purchase.

Hard to use

No real impressed. It's hard to suck through the straw. There is a lot of air in the cartridge before you drink. Can't be used without a cartridge.

Tumbler

Thought it was regular tumbler but one has to buy cartridges for it. I just want water not flavorings

Heavy when full and awkward to use! Leaks!

Heavy when full of water. Awkward to use. Very difficult to draw out the flavored water, if you have asthma or COPD forget drinking out of this! Very difficult and time consuming to wash and manufacture states you MUST wash entire tumbler every day and let it completely air dry for 24 hours! Not dishwasher safe! Oh and you must drink all the cartridge flavor within ten days or throw it away, so you're stuck with one flavor for days and days until it's gone. Don't recommend!

Highly disappointed

I got these thinking the straw is a good idea but the design doesn't work out the box and once a stopper is removed it works 60% of the time. It also doesnt use the whole flavor cartridge and leaves a good bit inside. I have a normal cirkul bottle and love it. I will honestly go back to using it only.

Disappointed

We bought 3 of these with high hopes. Unfortunately they are not easy to use, the straw is weird. The flavors don't always work as well.
