Description: Because Size Matter the Size Doctor Extender is a penile vacuum extender that can be modified and utilized as a penile vacuum weight hanger. This is one of the very few well-proven size extenders in the market that is actually backed by a scientific research found here. The Size Doctor can be worn by all men, as the gasket seals come in 6 different sizes, and the best news about this extender is that the gasket sheaths NEVER have to be replaced and are just as effective years after purchase. Many of the high-end vacuum extenders such as the PeniMaster Pro, theVac-Extender, and the Phallosan all require continual purchases of temporary sheaths and gaskets that wear out. This can get very expensive over time.
The dynamic SizeDoctor can be worn stealthily under your clothing as an extender device. It can also be modified to handle direct penile weight hanging to increase ounces to pounds. Conveniently Waterproof for hot tub or pool pleasure!
