*Handling FastSize Penis Extender*
It's going to come somewhat preassembled, with the first extension rods on already. If you need to put more on, if you're a little bit longer, you just screw the extension rods right in on each side of course, and then you connect the head (harness) unit on. What makes this whole system work is the springs in the lower portion of these extension rods that put constant force on the penis. You can see that when I push down, they push right back due to these springs. You can adjust how much tension by the rods but also by twisting the lower portion of the rods.
