Risks of penis extenders

Hello,

I just had one last question.

There are many articles warning about the risks of manually stretching and jelqing the penis. However, what about penis extenders like the Phallogauge extender? Do those penis extenders carry the same risk, or do they have less?

I would better use a regular extender. They are not much risky… at worst you can have a bruise, a blister… nothing like that will leave you impotent, but phallogauge in particular looks totally ineffective to me.
