Best $250 investment of my life. Being a old man that had erectile dysfunction and has a hard time getting an erection, this machine/toy has saved my sex life. I can take my small limp shrunken 1-2inch dick and just insert it into the fleshlight glove hole and turn this on and I get a hard one within 20-30seconds and stay hard till I cum. I love this machine it's perfect for edging for a half hour if I can hold off that long. Absolute best stroke/suck machine ever invented.
