Like everything about this mug. I mostly drink iced coffee. It keeps my iced coffee at very cold temperature throughout the morning . The little bag is also very handy .
This is now my go-to mug at home or on the go. Even with the lid off, it keeps my coffee nice and hot while I'm working from home. Love the feel of it when I sip, too!
Fun fact: I poured cold water into my Carter mug from our water cooler and then sealed it with the Carter Move lid. I opened it up a little while later to find ice had formed across the top of the water's surface.
Good insulated tumbler for keeping coffee or tea warm. Lip edge is too thin and sharp when drinking. Could be thicker like my ceramic mugs. Might be better for cold brews and iced teas.
