Help from anyone who uses a pump-up prosthesis, please

Thank you @MicheleR - good to hear that you are happy with it. The weight changes was not something I'd thought about but that is relevant !  I saw they are $500 instead of the $400.  I am thinking of the A..... Natura Xtra Light Adapt Air.  I guess with air in the back it has to feel softer and fit in with the lumps and bumps.  As my top area has sunk in I am looking at one which has more at the top.  Thanks again.  💖
