... had trouble keeping this on my knee but much better than a standard ice bag
I had trouble keeping this on my knee but much better than a standard ice bag.  No way I  could get up and move around with it on.  Would be better if the back of the knee could also be iced.  Did get the front and sides of the knee cold.  Runs very small.  Measurements in the description would help.  I did appreciate the email from the company telling me how to use it.
