When using a ProExtender, the penis is connected to a stretcher in the area of the glans. The extender is connected to either a rod or a strap system, which in turn exerts a pull on the penis. With the ProExtender (belt system), the belt is placed around your own hips and the penis is stretched. With the 
Penimaster Pro (rod extender) a stretching is achieved by the extending elements of the extender.
In the long run, the stretching is intended to stimulate the cell growth of the penis, which results in an enlargement.
In general, it is important that the penis extender and its materials are of high quality and that the device is very comfortable to use, as you will eventually wear it for a longer period of time. With the poor quality extenders, bruising or rashes can occur due to poor workmanship/construction after long periods of use, and you will want to avoid these.
A good quality of the penis extender also ensures that the device has a long life span and you will not have to buy spare parts.
