The Jes-Extender works by taking advantage of a naturally occurring process in the body – that of cell duplication. It’s the same process as building muscle in the gym – as you lift weights, you stretch the muscles you’re training by causing microscopic tears in the muscle, which causes cell duplication as the muscle heals and then builds
The Jes-Extender consists of four basic units
Anatomically correct rings in a circle for the base of the penis.
Two spring-loaded arms, attached to the base. They come with round screws to adjust the length of the width.
A special molded support
And, a soft adjustable silicon tube that holds the head of the penis while traction
Special extension rods are also included to extend the total length of the device up to 4 inches. This will be in use as the length of the penis increases.
How to Use it?
First, assemble the device with the appropriate number of extension rods so the entire length of the device is a bit longer than the unerect and gently stretched Penis.
Loosen the silicone tube and slip the device over the penis.
Before fastening the tube behind, press the spring bars then tighten the silicon tube to get a grip at the head of the penis.
Men who have not been circumcised should fit the silicon tube just below the glands with the foreskin either emplaced or rolled back whichever they find more comfortable.
The ends of the tubes are pressed into the two notches to prevent them from slipping.
After that, use the screws to fine-tune in the length and adjust the degree of traction. Make sure to adjust on both sides at the same time so that the device doesn't bend.
You will see three marks (900g, 1200g, and 1500g) on the spring-loaded arms which indicates the degree of traction. The further the arms are depressed the greater the traction. But, an overdue of the degree of traction is not recommended as you can injure yourself.
For the first two weeks of use, the traction should not exceed over 900g.
Make proper adjustments in the degree of traction by using the screws to regulate the length. Once the threads on the rods are visible do not unscrew any further or the device will come apart. to avoid that you can attach the extended rods to get the desired length.
To remove the device, simply release the silicon tube and slip-off the device. Also, a special protection pad is included with every Jes-Extender which is used to cushion the silicon tube if that becomes irritating for you.
To protect the device, the entire device should be washed in lukewarm water after each use and dried properly.

Traction and duration of use are then gradually extended week by week. Because the Jes Extender is completely safe to use, the length of use can be determined by the user individually.
