Dear Team
Satisfied customer here, so thanks! 
I recently received the steel shaker, and Im not gonna use it for two reasons:
- Its too large. The small plastic one is perfect!
- Steel is cool, but it also gets really cold if you, like I do, add ice to your shake.
Im just here rooting for a -400ml thermo steel shaker, that would also keep a prepared meal chilled longer, which would be great for bringing lunch to work.
Thanks in advance!
