The feature that stands out most in the Vivid Purple passion™ is the bulbous shaft that widens downward. This facilitates insertion and the bulbs work to make every penetration feel like three. Don't be intimidated though; the soft touch and pearlescent feel of the shaft makes each insertion smooth and pleasurable. This unit also sports a non slip easy touch four speed controller that's works on up down buttons. The Purple passion is waterproof, so take it in the shower and spend some quality time together.
