  1. I have been wearing Sizegenetics extender for 4 months now and I have gained 0.8 inches in length. I’m happy with these gains. I was wearing the extender for 8 hours per day.

  2. Sizegenetics really works, believe me, but it takes time. After 300 hours of wearing I have gained about 0.3 inches in erected state.

  3. I wear it two times a day – 4 hours in the morning and 3 hours in the evening. I use 1200 tension mainly with a comfort pad because I found out that the silicone noose is bad for circulation.
