About a year ago we ordered a new toy (a Zeus Electrosex torpedo plug, see picture below) to go with our MyStim electric unit. Unfortunately, Lance didn't spot that the connector was incompatible. However, while rummaging around on the internet recently, he spotted a Mystim to 2.5 mm plug connector and ordered one. It arrived yesterday and he tested it and it worked. We are now looking forward to trying it out over the next couple of days.
