Leaks around seal
When placed around the thigh above the knee the seal does not properly seat due to the hamstring tendons at the back of the thigh.  It is less of a problem if it is placed even higher on the thigh.  The problem is caused by the rigid ring supporting the sealing membrane.  Other cast covers have a wider and more flexible sealing system that better conforms to the lower thigh and fully prevents leaks.
