Love this and can microwave it.
- Familiarity: I've put it through the wringer
I looked and looked for this sort of cup. I use it at home for hot drinks, and can microwave it (the inner cup - it's sort of a ? whether the outer one or the cap are microwaveable, but I don't bother). It's also very versatile. It's not water tight, but it is spill resistant (PR says splash proof) - that is - if the cover is moved over the opening, it only drips out if tipped over. This is fine for my uses and makes it very easy to open and drink from. Pretty durable too.
