Rob perhaps a video on this might be an idea, I don't understand the whole concept, maybe you we can get Russ to do a quick video.
Russ you da man!
A pic would be fine.. o ly need to worry if your nipple is leaking. If it is you would have juice all under the delrin and on your battery and contact pin.
Its either is leaks or it dont. One would notice right away. I don't think it's something thst happends down the road.
