I like old fashioned tools, and this ice Pack is one. It is sturdy and well designed using a proven form. I love how it is easy to load and had a nice cloth cover bonded to a rubber bladder. It does not leak, even after letting a 4 year old play with it.
My wife is appreciative because she thinks I got it for her. In reality, I got it so that I could have a way to have ice packs without having to buy those ammonium nitrate ice packs that are a one time use. I think those type of packs are better suited to making homemade tannerite.
Anyway, as the video shows there really isn’t much to this ice pack, it just works.
