Nothing to report this water bottle makes his job: - The polar case provides a really nice touch - The neck is really very convenient to pour hot water without burning - Hot water obtained by putting the maximum at the mixer tap is sufficient: the kettle is still hot in the morning!
In short, if you are afraid to be cold at night, you know what to buy.
If you want to offer someone, put the kettle directly into the bed, is more original than to offer it in a gift box :)
