Highly recommended. It isn't just spill-proof, it's airtight. No fiddling with caps when you want to drink, and you can't forget to close it when you put it down. When you pick it up the button to allow drink to flow falls naturally under your fingertips.
Because it's airtight it keeps drinks hot for longer too. If like me you drink black coffee you will need to add a drop of cold water to any boiling drink, otherwise it will remain dangerously hot for a long time (unlike the similar mug I used before that was not airtight, so took the edge off boiling drinks by the time I started drinking.)
A Makeup brush? What a second, the GirlyMan thread is in the colored keys post.
I use a acid brush. Geek and proud of it.
Shaving foam brush also works, but my favorite is the cleaning brush that came with an electric razor I have.
wow, you actually use a straight razor?
Yes, it's not so difficult or dangerous as you might think.
The only real obstacle is honing the blade (knowing what to buy and learning how to do it) or finding someone to do it for you.

I just started using a safety razor. It can be unforgiving for the first few days : )
