Form 4 provides exceptionally powerful vibration in a shape that adapts to the body. This design offers the perfect balance of Power & Flex. Though strong and firm, it also has a bit of give just like a good partner. While the shape adapts to the body, the over-sized motor provides exceptional power, exactly where it’s wanted most. Four vibration modes and 5 power levels bring exceptional power with a flexibility that allows for G-spot, internal and clitoral stimulation. Just place Form 4 on the charging base for no-fuss, no-cord recharging.
