Bought this mug to fit inside of my Mytistax large pot (1200ml) along with my stormin stoves cone and stove, the mug is great quality and insulated to keep my drinks hot while I cook a main meal, The no spill lid seems to work fine.
It's good about volume for a mug and keeps heat not that much long if I compare to others but still okay. Only thing is lid is not fitting/holding strongly and it's really easy to come off.
What good is an insulated mug full of red hot liquid with a lid that don't fit . The lid just rests in the top and the seal hardly grips it at all . Dangerous in my eyes , I expected so much more from sea to summit very poor .
