Evolved Robust Rumbler

Silicone Over a Firm Core

Most rigid vibrators leave their hard body exposed. This one is fully covered in silicone, with a soft outer layer over a firm inner core. The surface gives slightly under pressure while the shape stays solid.

The bulbous shaft swells to a rounded profile, then tapers toward the tip. It measures 7.75 inches in height, with a depth and width of 1.5 inches each, so it sits in the hand with a noticeable heft.

Seven Speeds, Five Intensities Each

An extraordinarily robust motor drives the vibration, and a split 2-button base controls it. Seven speeds each run through five intensities, so the range moves from a light hum to deep, rolling pulses. The two buttons are separated on the base, which keeps adjustments easy to make without looking.

• 7 speeds with 5 intensities per speed
• Split 2-button base
• Extraordinarily robust motor
• Operates quietly

Charging, Submersible Use and Warranty

The Rumbler charges by USB, and the USB cable is included. It is completely submersible, so you can use it in water without worrying about the body. A 5-year warranty covers the unit.

This model has been discontinued, which matters if you are comparing it with other rigid vibrators that are still available.
