    Eric and Joe - I've seen but not filled any of the bubble units with the fill port on the side. I think these are the older model chambers.

    Im not sure what the reference to MHR1s is - that is a cylindrical slide rule. 

    Be careful with fluids for the chambers. A lot of low viscosity fluids can eat seals. The good thing about silicone fluid is that it's inert. 

    Joe, I'm curious how you sealed the leak in the bellows. Could you do a write up?
