This device is NOT a sexual toy (vibrator). Do not expect intense vibrations. We are using soft sonic waves generator for light vibrations that improve blood circulation to prostate and pelvic floor muscles (patent #CA 2730809).
I HAVE TRIED JUST ABOUT EVERY PROSTATE MASSAGER OUT THERE AND THIS ONE IS NOW MY FAVORITE...THE SONIC WAVES PENETRATE DEEPER THAN A REGULAR MASSAGER ...IT'S GREAT THING.
