VeDO's Quaker Anal Vibe in Midnight Madness features six graduated swells and twelve customizable vibration modes, all wrapped in a waterproof, silken surface. Ideal for beginners and advanced users alike, the tapered starter bead penetrates comfortably, with four gradually increasing spheres leading to a firm, wide base for safety and precision. With one-button control, twelve vibration modes can be explored, from steady intensity to escalating pulses for any stimulation situation. The hypoallergenic surface is easy to clean and responds to body heat, but always use a water-based lubricant for smooth, enjoyable play. Features 1 AAA battery (sold separately) and is waterproof.
