Saves electricity, so saves money.
Bought this to save continually boiling kettles of water through the day and wasting electricity. Now I boil a full kettle in the morning, make a wet of green tea and put the remaining water in the flask, when I want a wet again I just top up, as the tea leaves are good for the day, and the water is still well hot hours later. I would say this vacuum jug is more efficient than some S/S flasks I have had, certainly keeps the water hot for the day. Highly recommended.
