The one I normally use has fallen apart (the bottom broke off) and I want to get a new one.
1) Not made in China. I am on a mission now to find one that isn't. This is proving to be my hardest challenge. I have found Malaysia on some of them, so that would do.
1.5) Certified BPA free if plastic
1.75) Dishwasher safe
2) Can fit in a car cup holder of standard size.
3) Good seal on the top.
4) One hand operation, as in I dont need to unscrew it like a thermos when I want to drink from it.
5) Keeps things insulated for a couple of hours. Some of the mugs out there are paper thin and are no better than a paper cup.
