Yeah, it works OK.
I found some 3-4 years ago this odd-looking device in the net.
As poor as I am, made one for myself using the picture in the net.
Model one wasn't very good and needed modification, but mark II works like it should.
The liquid coming out from my penis after first uses looked sick.
Ten after some usage,nice looking sperm comes out and the massager is no longer needed.
Recent test was very good no sign of coming problem!
