Was looking at a new travel mug to replace my Frank Green which I've had for a few years. A little tired of constantly dismantling to clean and leaking when the lid mechanism is only partially engaged. Received mine yesterday and so far quite happy with it. Many reviews commenting on poor insulation - but I feel they may be reviewing the non-insulated plastic versions instead. Lid appears much easier to clean and I like how the size resembles an actual coffee cup that can fit under my coffee machine group head rather than the super tall Thermos designs often seen. No leaks so far so I'm comfortable throwing this in my bag.

Regarding insulation capabilities - overall not bad at all, on par with my Frank Green stainless steel insulated one and much better than similar plastic or glass reusable cups. All cups started with 250ml of 91˚C water within them, ambient temperature 23˚C (so differences may be even greater in colder environments).

Is the inside just stainless steel? Or does it have a nonstick coating?
