A major drawback is the short shelf life of the bottle.
For me, the hot water bottle in winter is really in use every day, that is. it is really used much.
After a few weeks but it is regelmäig broken and cracked in the material. Most at the base up.
As it happened already, unfortunately, often lead to painful burns when hot water has leaked.
Meanwhile, I had already determined 10 hot water bottles, which has been a problem.
I have last year therefore wrote to the manufacturer and they told me briefly that I would get when sending in the defective hot water bottle a new one.
But since I had to wear yourself the postage costs, we have not done this and again bought a new bottle.
Nevertheless, I buy this hot water bottle again and again because I am otherwise very pleased with her and unfortunately there is no suitable alternative for me.
For the price, it is also to cope with, that I have to buy a new every few weeks.
I think those who do not so often uses the bottle, which is likely to be very happy with it.

Since my first entry I have already the 3rd bottle. She's always pulled in the same place.
