Difficult to adjust with my arms, doesn't maintain cold for long time!
Since I'm a small person it doesn't fit me very well, it's difficult to accommodate with my arms<br />I put it in my freezer for a long time, but it doesn't maintain the cold for a long time, or other option I have to buy 2 more like these and to change them all the time, so the result is I need to spend more money. I guess I don't need them so much because a) not comfortable,  b) doesn't maintain the cold for so long.
