I recently tried out the Otto Bock Harmony E-pulse vacuum suspension system for a below knee leg. 
What I wanna know is are there other amps using this for a BK?

I was previously wearing the Harmony TEC vacuum leg and made the switch because of lighter materials and that Harmony no longer supports the model I was wearing (i.e. no replacement parts).
 
So far as I can tell this system with the electric pump will not work for the BK because it is virtually impossible to keep all the componets running without a leak.  tis is aside form the cosmetic considerations of who wants flashing lights and loud beeps and motors announcing "Hey, I'm an amp!".
 
What sleeve keeps the vacuum in?  I'm wearing an Alps sleeve with tape and a collar at the bottom but it keeps springing leaks.  With the Harmony TEC the TEC sleeve wouldn't even last two weeks before the socket would wear through the sleeve at the wings.
 
Please write me at my e-address if you have this system and are making it work or if you have ideas.
