I love the pretty hot water bottle covers. That said, I do not like the hot water bottles, themselves. The vanilla odour fills my bed - I find it sickly and almost suffocating. The neck of the bottle is not round and self-supporting, so it has to be held open while pouring hot water into the bottle. This is an obvious hazard. I had originally admired the 'holding handle', but see that it is not useable - not even for hanging, because one should hang these things upside down to drain dry. I bought two of these; currently, they are 'airing' in the hope of losing the vanilla odour. A final comment - I bought hot water bottles because I need to use an electric adjustamatic bed, which precludes the use of electric under blankets, in case the cable gets crushed. I don't like over blankets, they are too heavy. I reverted to old school hot water bottles and thought I was spoiling myself with these . . . so am I disappointed? --- yes.
