The FastSize Extender device promises results, but it's far from quick and easy. Just ask Bob, a retail manager from New Jersey. He says he's gained over 2 inches of erect length. All it took was 25 months and over 2,600 hours wearing the device, typically five hours a day, seven days a week. "I was afraid my girlfriend would think I was a freak, but she was supportive because she felt a difference in her satisfaction and I felt more confident in myself," Bob tells WebMD.
“I have personally recommended this to men and I have received lots of great feedback regarding its long(er) term use. It’s a hydropump, so it works by using water when you’re in the shower or bathtub. To fully understand this, it’s important to know that the penis has three soft chambers, the corpora cavernosa (two large one’s on the top of the penis) and the Carpus Spongiosum (a smaller one on the bottom of the two). When these two fill with blood, you get an erection. What Bathmate or a penis pump can do is expand these chambers, thereby allowing more blood to fill in."
