Review on 🏀 OPTP Posture Ball 8-Inch (475) - Enhance Physical Therapy, Exercise, and Fitness with Foam Roller Massage Ball by Jane Burns

Although this ball has been a life saver for my neck (rolling over the ball twice a day) it has slowly become egg shaped since I bought it about 14 months ago. I manage to work this "egg" by rolling it together, but then it doesn't even press down on my spine. When this egg rolls sideways, it doesn't deliver enough pressure because it has too large a radius on its "flat" axis. I could buy a new one every year but I think I'll look for another brand that's made out of a better non-memory material like polyurethane. I think I expected it to last longer.
