Re. Frank Green cups, I have the standard one which is great, but now wondering about the Stainless steel version, what's the insulation like? thinking of getting one for my good wife, she has a keep cup but she ain't a fan, and something that can retain a bit of heat would go down well.
It's good, not thermos levels, but it keeps my coffee still almost the same temp as it comes out of the cafetiere when I put it in my bag and forget to drink it until I get to work.
