Has anyone here tried the topco tommy gunn cyberskin extension? How does it compare to the ones above? I have the TSX three inches extra and it's great, but my girl wants something with real-feel skin that's not floppy at the end. It's a shame this market hasn't developed much since 2009! Www.rxsleeve.com sells amazing looking ones but they're so expensive! $1000! Does anyone know where I could get a realistic one which is fairly firm and not HUGE, 6" circumference, just like the TSX?
