Help with extender JES extender

Just purchased a JES extender and I’m having a problem with the traction measuring mechanism.. When I put on the extender I can’t seem to get it to apply any traction. What I mean is, when I put it on it doesn’t seem possible for the device to gain any traction while adjusting it, even when having it strapped so tight it’s painfully uncomfortable. When adjusting the rods will extend but the traction will still show 600 (the lowest possible)

Any suggestions or ideas what is going wrong?

Buy a different extender would not wish the JES extender upon my worst enemy. Had nothing but trouble, pain and discoloration with that ‘choker of penis heads’ product. The noose and the comfort strap are in my opinion almost worthless products, pure garbage. Just sayin.

I got a jes extender, and in the begging I used to feel a lot of pain, but as they recommend if it hurts stop, make the blood flow, rest and put it again, I was really stubborn and now I’m used to it, of course as soon as I get money I will by a vac one to match with my jes extender, but enough of this, I will tell the way I used it, I put the rod size the same of my erect cock 5 inches NBPL so I wouldn’t need to roll it to make more traction then after a month I increased 0.5 cm on traction and it has been working for me
