Cirkul 40oz. Pearl Stainless Steel Tumbler with Handle, All-Day StrawSip™, Double-Wall Insulated

Its not a STANLEY but it serves the same purpose. I don't like drinking plain water and this is perfect. The lid doesn't let anything drip out if it rolls over. Size is great 40 oz so 2 reg water bottles. If you fill it 3 times you went through one cartridge. I don't like fake or overly processed flavors. so its nice getting just enough and being able to control the amount of flavoring i get. I'm happy with the cartridges for now. I haven't been disappointed yet. I've been drinking considerably more water because of this bottle. Its built really well, so not disappointed. Its hit or miss on the ice retention. you have you balance out ice to water. The bottle actually keeps stuff pretty cool. I'm definitely OK with that. it does fit in most if not all the cup holders i have had to deal with.

Super happy with this cup!! Tried to buy it locally at 2 different stores, neither had it in stock. The lid can be fit for left or right hand, keeps ice for a long time and works like it should!! Absolutely recommend. Looks amazing too, as it matches my watch, earrings and uniform at work!! What more could I ask for!!!

Omg I love this it’s cheaper then Stanley and better quality and leak proof also easy to use just pick what flavor u want add water and sip away. The only thing I don’t really like that the taste goes away fast. But it’s better then drinking other bad stuff

This water bottle works pretty good! It is a little heavy, but it is sturdy. It is hard to get water through the flavor cartridge. The taste of the Cirkul flavorings are always good, but that doesn't affect this cup.

Yes, it was hard to sip out of it for the first week as the silicone parts broke in and loosened up, but after that it was perfect. I washed the parts with hot-ish water every day (not boiling hot) and it loosened up over time. I fill it up in the morning with chilled water out the fridge and it stays cool all day, I don't even need ice! The chameleon color is beautiful and I feel so proud holding and carrying my giant water container around the house. My husband is happy too, since I was always so bad with water intake. But not anymore!

Love the concept. Struggle with getting flavor when sipping. If you tip it, it sometimes helps but is definitely inconvenient to have to tip a 40oz tumbler every time you take a sip. Cleaning is easy and is leak proof. Good value for the money if it worked correctly but not very easy to use, needs to be better quality

Got this instead of overpaying for a 20/22oz clear bottle package at the store. I got a color I like and it is 40 ounces!!! The handle is awesome and ice lasts all day. For anyone new to Cirkul the filters should last for about 2 whole fills with this!

The media could not be loaded. I love the colors! My favorite so far. It is heavy, FYI. Works well with the flavor cartilage and holds 1l of water. Has an option for left or right handed people and so far leak proof. Feel durable, great price for it, easy to use. Recommend this color for anyone. The flavor cartilage are okay. They last about 4l of water at level 5 on the flavor. Then at the 5l I have to turn it to level 9. Definitely will continue to use it as it have helped me drink more water.
