I'm in chiropractic school so I really needed a good model. The product's name speaks of its flexibility, but to be honest there isn't much flexibility in it. Also, the SI joint is practically non-existent and I'd really like to move that area because it would be very helpful if I were preparing to practice certain lists. The ilium is mostly bolted to the sacrum, so I can't do much in that area. It would be easier for a student to visualize honestly since many students like me learn visually…
