I just got my Zojrushi thermos two days ago, and today I decided to put it to the test. I picked up an iced Café Americano at Starbucks this morning (they even filled the thermos for me!) and waited for my results.
It's been about four and a half hours now, and the ICE NEVER MELTED. The coffee never got watered down. I'm calling it, Zojirushi thermoses are the real deal. Thank you Bombcast, you've given me the Thermos of choice. And it's finally back in stock after that post-Bombcast shortage!
Anybody else pick up a Zojirushi thermos yet? Any chance you have photos of your Zojirushi success?
