Fellow 20 oz Carter Carry Vacuum Insulated Tumbler for Water, Tea, Coffee, Smoothies, & more - Stainless Steel - Keeps Heat for 12 Hours/Stays Cold for 24 Hours-Leak-Proof Seal-Slim Width-Peri Twinkle

I love the Fellow Carter Fellow Carter Carry Vacuum Insulated Tumbler. It keeps my drink cold until I refill it and probably a lot longer if I left it alone longer. I drank a coffee out of it and it stayed hot until I was finished drinking it. It is very nice looking and seems to be of high quality materials. I chose the Periwinkle color as it was a bit less expensive and very pretty. It’s a bit heavy but I don’t mind for higher quality product. It is easy to use and take the inner spill guard out and put back in.

A great tumbler. My water remains cold and i love the sturdy handle. it's very easy to use and clean.

This was a Christmas present for my wife and she LOVED it! It would be nice to come with something to clean it with.

The product is defective after some use, the inside lining (ceramic coating) breaks into pieces , I didn’t know till I pour the water out into a red cup, and seeing white stuff floating in the cup(Jan.1 2025)I am horrified, how long had I drinking the white stuff like this ? I repeated the steps over and over, putting new hot water in then pour out , more n more white stuff comes out with water. 🥶🥶🥶🥶Do not buy any of fellow mug products .Update: the company said going to ship out a replacement , I’ll update with the post see if the product will withstand the regular usage (hot water). 🙏

I absolutely love this my juice stayed cold fir more than 24 hours I have cubes of ice after a long day I love it

I love this Tumbler, my coffee has stayed the same temperature for 6 hours. It is easy for me to carry around thanks to the metal handle. As a college student always on the go it is hard to carry everything I need plus a coffee cup & now my problem is solved thanks to this awesome tumbler. It is a bonus that it is super cute and trendy

I have several Fellow products and am always very pleased. This tumbler however, does not keep my tea hot/warm for very long at all. I tried to set it on my electric mug warmer and that did not make a difference. It doesn’t seem to allow the warmth through the ceramic. I will keep it but don’t like it very much. It is pretty though.

I have had one of these for a while, but had to get this one as it has a nice and sturdy handle on top. Also... the purple color is beautiful!Only drawback..the 20oz one I got doesn't fit under my ninja coffee brewer, so i do have 1 extra step when taking coffee with me.
