A classic, perfectly beginner friendly pump that deserves a place in any man's arsenal of enhancement tools, this simple, effective Power Pump is incredibly user friendly, made from body safe materials, and is an overall great choice for the type of stamina increasing, performance boosting effects you'll only get from a top notch penis pump. The classic cylinder is transparent with a hint of color so you'll be able to watch yourself grow, and you'll do so in supreme, pleasurable comfort, thanks to a soft, supple PVC entrance that cushions and stimulates while producing an airtight seal. You'll love how it feels, the smooth material warms quickly to match body temperature, further increasing your enjoyment, and in turn, the erection-enhancing effect. To get things going, simply squeeze the medical style pump bulb until the desired level of suction is reached. The unit is ultra easy to assemble, and disassembles just simply for thorough cleaning. Compatible with water and silicone based lubricants.
