Maximize your pleasure, size, and confidence with the Enhance Travel Pump System. This convenient, compact, and discreet penis pump is designed to keep your workout routine on track, whether on the go or at home. This penis pump works by using a vacuum-like system to create an airtight seal that increases pressure and blood flow. With regular use, the increased pressure and flow can allow you to reach your maximum length and girth potential. Universal measurements on the cylinder allow you to keep track of your progress while you pump. A tapered silicone donut rests on the base of the cylinder to create the ultimate airtight seal, secure suction, and comfortable pumping experience. To use the Enhance Travel Pump System, just use the finger-grip handle on the hand pump to pull air out of the cylinder until you reach your maximum pressure threshold. The quick release pull tab valve allows you to remove the hose without losing suction for a totally hassle-free pumping experience! When you’re ready to release the pressure, simply depress the quick release valve for instant release. Your Enhance Travel Pump System comes with the Silicone Commander erection enhancer. To use your Commander, simply slip it over the base of the cylinder and pull it seamlessly onto the base of your shaft when you’re ready to switch from pump to play. Keep that rock-hard erection going strong without a moment’s interruption! When you’re finished pumping, the handy travel bag makes it easy to pack up your pump until your next session. The threaded two-piece cylinder easily unscrews and separates for compact storage. With easy disassembly, a convenient storage pouch, and a silicone erection ring, this pump system has all you need and more!
