Had these warmers ordered because of its size for my son and also equal tried (degrees despite almost 30, my son is addicted to hot water bottles) When you first use everything was soaking wet in the morning! Since summer is the water was not so hot and put them in a big stuffed animal -Bezug, so he has not burned for luck! This is sometimes not, a, hot water bottle, which is not tight, not to paint what could happen because, at a degree Kinderwärmflasche !!! Did not complained, hope then get a perfect product!
