Let's hope we are not going to suffer another winter like the one we had previously because it is going to be hard. One thing I hate is to feel the cold when in bed. With this hot water bottle with cover at least those winter nights will be fine. The hot water last till the morning with the cover (I am an expert on these items) and there is not risk to be burned when it is freshly filled. The penguins add a little funny touch. This is a perfect gift for who is flying home for Christmas, because it is light, flat so great to store in a suitcase. And a hot water bottle is not useful only when it is cold, even when we are not feeling well it is a nice object to hug.
