This tumbler is really cute and very functional. I love the metal lid and the encouragement on the side. I use it around the house all the time. The only issue I've had with it is the rubber ring in the lid became unglued/fell out after a couple uses. Not a huge deal though, just put back on and go!
This cup is so cute and holds more than I expected it to hold. The only drawback is that it doesn't fit into most vehicle cupholders, but I don't mind that.
