M For Men Robo-Bator Vibrating Automatic Stroker

They're controlled by separate motors, so you can run vibration alone, stroking alone, or layer them together. The turbo boost kicks both motors to maximum intensity when you press and hold the button.

The seven stroking patterns range from slow, steady rhythms to quick bursts and wave patterns. Each has a different speed and intensity curve, so you can match your mood or build toward the finish you want.

The inner sleeve has a snug but comfortable grip that works for most sizes. It's not adjustable, but the soft material gives slightly under pressure while maintaining good contact.

Pop the sleeve out, rinse with warm water and gentle soap, then air dry completely. The sleeve is the only part that needs deep cleaning — just wipe down the motor housing with a damp cloth.

It's audible but not shocking — about the level of an electric toothbrush. The stroking motor makes more sound than the vibration, especially on higher settings.
