I wanted a really good coffee mug, heavy, the kind found in diners. This mug absolutely fits the bill. It's thick walled, sturdily made, goes through the dishwasher beautifully. The mouth rim is rather thick so I always have coffee dribbled down the side, but I do at diners also.The mug also fits perfectly under the keurig and keeps the coffee warm longer, probably the thicker wall design in the cup.I shopped around and didn't end up buying these from Amazon, but it's the same diner mug. You just can't go wrong with the simple and sturdy design of these mugs.
