I've owned this mug for almost 2 years now. Today it was in a bit of an accident.. (and it took it like a champ!) My boyfriend accidentally left it on the roof of the car when I took him to work. Oops. Didn't even realize it until halfway to work. When I came back about an hour later, our beloved coffee cup was on the road about 20ft up the street. It had very much been hit by at least one car, but knowing how much traffic we get, I'm sure it was more than one. Now, I'll admit, the lid is gone completely. I believe it's in a different dimension unfortunately. Which is fine, because the cup is no longer completely round so surely the lid wouldn't fit anyway. However, I'd say this mug did pretty darn well for playing in traffic for over an hour this morning! I knew it was a tough mug but woah! I highly recommend this mug and will be buying a replacement one so the boyfriend has a good mug with a lid for mornings. However, I fully intend to wash this one and continue using it in it's slightly disheveled state. The scratches and dents add character!On top of being extremely durable, it keeps my hot beverages nice and toasty for hours, and I've used it to keep ice chips in for hours as well. It's super easy to clean and the handle fits nice in my hand. This is my all time favorite mug honestly. (Hoping it still keeps things hot in its current condition, we'll see ??)In summary, 1) Buy this mug. 2) Be sure to securely fasten it inside the vehicle before driving! ??
