Dr. Joel Kaplan’s Hand Pump System for E.D. effectively treats Erectile Dysfunction by helping you achieve and maintain an erection for sex. You will get an erection every time you pump. Using vacuum pressure, the pump brings blood-flow into your penis, giving you an erection every time you pump. Your erection will be bigger and harder than what you naturally have, as the pump increases blood-flow into your penis. The 2.00 inch cylinder is made of the finest, medical grade acrylic. It is tapered toward the top to match the natural anatomy of your penis. By rolling a ring over the base of your erection, you can maintain your erection until you take the ring off. (We recommend wearing the ring for up to 30 minutes.) Unlike prescription drugs like Cialis or Viagra, you have FULL CONTROL of your sex life as you can use the pump whenever you want, as often as you want. Pumping to achieve and maintain an erection is a completely painless, and even a pleasurable experience. What’s included: Hand Pump, Safety Pressure Gauge, Erection Cylinder, 3 Silicone Erection Rings (3 sizes)
