My old ball I had for over 2 years was cracked and old and developed a hole where the stuff inside was coming out the night before I ordered a new one on 鶹. It was a life saver to have it delivered so soon as my legs swell up so quickly with my compression stockings on. This time I will wash it more often and keep it out of the sunlight to see if it lasts longer. This ball helps me to keep my independence so no one has to help me because the other systems available kill my back to use.
