Well, I bought the original one too, there in Germany, and after a month it started to crack and I had to throw it away. Now I have to make my own pumps because there aren't any in the size I need. I have some for pumping cock and balls at the same time and others for cock only.
That is the original Froehle Big Hoden-Condom combined with the Froehle electric vacuum pump - that is the best I've ever seen. With the special valve I can control the vacuum. So I was here for 6 hrs while pumping my member. Yes, it was a big load then ...
