I was introduced to this in physical therapy. I bought one to use at home. Rolling it back and forth with my feet and using it for leg lifts and crunches has cured my sciatica.
- How accurate was the sizing? Exact.
- Please tell us about the quality of the product. Very high. My nephews use this as a "Horsie" and bounce on it. It never loses air even from their bouncing. Durable.
- Was the product free of any manufacturer defects? Yes.
