This breaks the seal of the vacuum, allowing the cylinder and pump to be removed and laid aside. The user can maintain an erection for up to 30 minutes, wearing only the tension ring. This procedure, which takes about two minutes, is used whenever an erection is needed. Men who have had their prostates removed are successful with it. Men who have had penile implants installed and later removed can often use this system successfully, as can men with blood vessel blockages.
Psychological patients are successful with it, as well as diabetics.
The manufacturer of the System polls new owners to determine the effectiveness of the product. Over 200,000 men have been surveyed. Initially, it takes practice to use the System. An unexpected statistic which emerged from the survey pertained to the occasional restoration of natural erections. This means that the use of a vacuum device to force blood into the penis may have the effect of bringing back some sexual power, some of the time.
