Probably only slightly better than SizeGenetics... not that great. Hard to tell which is better.

A bit pricy but definitely worth it. I first tried SizeGenetics and Phallosan. Phallosan's condom parts didn't fit my penis well, so it either slipped out or choked my penis to death. The SizeGenetics was OK, but I got the cheap version and the noose part always choked out my penis. Not to mention I'm uncircumcised and I had issues getting it stay on. Sizedoctors did not have any of these issues, so I'm glad I switched over and finally found an extender that's not wasting my time.

First I tried the phallosan, but the condom parts broke... haven't had any issues with the sizedoctor yet!
