“I am impressed. This does not perform like a usual travel mug--you can't flip open the lid and sip whenever you want. However, it keeps drinks impressively hot for a much longer time than other name-brand premium travel mugs I have. The lid seals tight, too, so I've been able to carry it inside a briefcase/attache case or carry-on luggage without any leaks. That it is also visually impressive is a bonus.”
