Worth it. Get extras.
I love this mug! I use it at home b/c I don't drink my coffee immediately/quickly since I'm busy with two kids also. It keeps my drink warm just long enough for my mornings. They do break though. My friend broke one washing dishes. And I broke the inside bottom of one with a metal butter knife I was going to use to stir the drink (it wasn't a hard hit at all, must have just touched the right spot to crack it). I ordered more, and got a couple extras I keep stored away b/c I do imagine at some point they'll break (hopefully a long time from now). To be clear... we break our ceramic mugs as well (handles, shatter, etc) as well so this is no different. If you're looking for something that's constantly on-the-go and rough usage, then have a backup metal mug for that. I typically use this at home for breakfast and at my home work desk. I occasionally take it to the park when I'm playing with my kids or to the toddler's soccer game, but I'm always conscious of being careful in those situations.
