I tried it, at the suggestion of my prosthesist. In idea, I would think the system is superior in that you don't have the bottom of your residual being constantly pulled down (or having to hit the button to stop it) after being on your feet, etc. I would guess that for a person with a regularly shaped residual/knee that it might have worked really well. In my particular case my fibula is very prominent due to the breakage and caused an irregularity in the seal. The biggest issue was that it would occasionally just lose seal, burp air, and my leg fell off. I never had that happen with pin retention. For all it's other shortcomings, my leg not falling off is good.
