SizeGenetics

SizeGenetics is another contender on the penis enlargement scene, offering a package that they guarantee will increase your length and girth by 30% within 6 months or you get your money back. Like X4 Labs, they pay attention to the comfort of the wearer by providing a thicker, cushier strap rather than just a thin piece of silicone. The device is backed by doctors and clinically proven in a series of studies that are available on the SizeGenetics web page.

The device is made of medical-grade materials and comes with a set of spare parts to replace any broken pieces. The real drawback of this package is that at $350 for the device itself it is well, well over the price of some of the competitors who offer an equally good device. If you really feel drawn to SizeGenetics we strongly recommend you go for the more expensive package, as for only $40 more you get a whole pile of goodies, including a DVD of sexual techniques, another for massage techniques, and online access to a set of exercises and other activities.

One last thing that makes SizeGenetics different is that the more expensive package comes with a lockable box, which is good for keeping prying eyes away. Although now that you've seen this idea you could probably buy a lockbox more cheaply for whatever one you eventually buy!
