This thermos is amazing. It stayed hot for 1 1/2 days. It never leaks AND, after falling down a flight of 13 steps onto a hard tile floor, it didn't leak, break, or even dent - the handle and all remained as new! It's easy to clean with a drop of detergent inside, close and shake well, rinse and let dry (it is not meant to ever be washed in a dishwasher). The capacity is large enough for more than four good 8 ounce cups of hot or cold beverage in a day. Highly recommended and great value and longevity for the cost.
