This system worked when it was disassembled. Below is Otto Bock's description of their product. Vacuum volume management system that is Slimmer, lighter, lower-clearance than Harmony P2 for lower limb amputees who want a precise socket fit for confident movement all day long. Elevated vacuum reduces fluctuations in residual limb volume for precise fit throughout the day. 20% lighter than Harmony P2 for better user acceptance.
Lower clearance (4.6 inches/117 mm) so more users can benefit. Smaller circumference for better cosmesis.
