larry,
I think that the salt water or the epoxy may be causing some of the irritation.
The ballzinger does not need to any more help to work properly, and the process is not to get a larger voltage, but a small steady current generated naturally. Tom had tried the saline water a couple of years ago, and if at the beginning it seemed to increase the voltage, at the end the idea was dropped. There is no significant change if voltage. The zinger should be generating between 0.5 and 0.8V with or without the saline water anyway.
HJ,
I have been wearing mine for about two month now, and I feel the effects like everyone else. Harder morning wood, fuller balls, larger flaccid penis. When I am away from my gf’s, I try to hold masturbating, I enjoy holding back to give a huge load when I get together again. It is hard to please two gf at the same time!
I have not worn the zinger for the past 4 days because I developed a small rash at the bottom of the scrotum, maybe due to pinching or rubbing from the edges of the latex, but it is all healed now, and I will start to wear the zinger again. However, I have noticed that without it, I still retained the longer flaccid hand in the morning when I wake up, and very relaxed balls. My erections are still nice, but not as intense as when wearing the zinger. So the long term effects may be interesting to note.
