Used it to take tea to office, tea was warm after 4-5 hours in winters. Can carry around 3/4 glass of tea in it. Good brand. Its small about the size of my palm and can easily carry it in purse or bag. About durability only time will tell
It came in good packaging. I've been using it for a week now, keeps content WARM for more than 15 hours. It definitely keeps it HOT for 5-6 hours. It is worth the price. If you are considering buying, you may go for it.
