The supreme model of the ProExtender System is a newer, better, and improved version of the ultimate model.
It comes with reinforced material and aluminium rods. The device comes with an improved silicone noose strap which acts like both silicone tube and straps altogether making it a perfect grip onto the penis when worn.
The design and material of the penis extender device have been improved making it stronger and lighter in weight. This makes the extender easier and more comfortable to wear and use inside underpants.
The rods and screws are made of aluminum making them up to 30% lighter and stronger in weight.
