I'm afraid of hot water bottles when you put hot water, I had to, but after a while, there may be leaks and I'm terrified of receiving the 'Hot water. This hot water bottle filled with flax seed is very comfortable. I had hot water bottles with cherry stones, but my body is so painful that I could not stand the touch of noyaux..je know is stupid. There, the contact is moelleux..tout what I need. I recommend another next month (for neck). And in view of aesthetics is a product that can soffrir. Thank you +++++
