A jelqing device is a device that mimics the hand gesture of a traditional jelqing exercise. A jelqing device is traditionally made up of two sponge-like rollers attached to adaptable handles that fit properly for any size penis.
The advantage to using a jelqing device to enlarge your penis over a more hands-on approach is that you have even pressure over your penis, allowing more symmetrical results to happen. Although jelqing with your hands will provide positive results, some people just aren't as "in touch" with their penis and would rather use a device than playing with their dick all day. We don't feel that's a problem though.
