Fully stocked with absolutely everything needed for an amazingly effective, breathtakingly pleasurable and ultra user friendly pump experience, the Hydromax Extreme contains not only a crystal clear version of the innovative Bathmate pump, but also a host of accessories, including lubricant, a high end measuring gauge, plus hose and pump ball attachments for even more enhancement options.Harnessing the natural suction created by water in your tub or shower to increase the strength, health, size and overall appearance of the penis, Hydromax effectiveness has been praised by male sexual health experts, various men's health magazines, and many, many happy customers. The theory behind this great system is simple, once the penis is in place and comfortably surrounded by warm water, you'll push down on the cylinder, activating the pump bellows to naturally create a suction effect. Gentle yet definitely effective, the following pressure draws blood into the penis and surrounding tissue, creating a firm erection and in essence providing a workout for the male sex organ, keeping it in shape, so to speak, and operating at peak capacity. Even if you're a complete newbie, this pump is by no means intimidating and use is virtually effortless, the Extreme even contains a comfort insert pad that helps the penis slide in with supreme comfort. Once in the tub or shower, you'll flip the gray pip at the top to lock in water. fill the inner cylinder with water and insert the relaxed penis inside. There's a slanted side to the comfort pad ring, this should be placed against the testicle area (making sure testicles are clear of suction!) to avoid unwanted pressure in that area. When the soft foam comfort ring is evenly placed around the base of the penis, unlock the valve and begin pumping. You may need to repeat this step a few times, optimal suction occurs when the bellows remains depressed, at which point maximum pressure has been reached. Then, lean back and relax, letting the suction do its work for a few minutes, best results seem to occur with this process repeated 2-3 times over 12-20 minutes. If at any point you experience discomfort or pain, you can immediately eliminate pressure by pushing the quick release valve at the top point of the pump. Your Hydromax Extreme set starts with the pump itself, an extra sturdy polycarbonate cylinder marked off into both metric and imperial increments along with a pliable, skin safe synthetic rubber gaiter base and stainless steel spring release valve up top. It's 29.5cm (11.6 inches) in total, with 8.5cm (3.34 inches) of diameter. The maximum penis length that this pump will accommodate is about 20 cm (7.9inches), and the maximum girth is about 4.6cm (1.8inches) in diameter. Fitting snugly inside a sturdy, lockable case containing the rest of the set's offerings, the Extreme rests beside a comfort pad, a hand ball and hose for a more manual option. A shower strap takes some of the burden off, while a unique shape-form measuring gauge allows for accurate result recording. When the session's up, a cleaning brush with long handle easily reaches down into the cylinder for quick clean-up. All this zips securely into the discreet hard-wall case that can be locked up tight with a tamper-proof paddock with a programmable security code. A full color, ultra detailed instruction manual is included.
