I´ve been using mine about 2-3 times a week, and yes sometimes I like to have full day sessions and some of my edging sessions have last for 4 to 8 hours. The longest sessions has been over 9 hours.
Love using Venus at slowest speed. V2K is just awesome and can give strong and wonderful orgasms.
V2K must to have for men.
Have owned Venus2000 for over 14 years.
