This controller is part of the Sterling Collection, a line of interchangeable controllers and bullets that can be mixed and matched to create the optimum combination of power, settings, and toy shape. The 7-Function Dual Controller is a sleek, metal plated controller and battery pack. The ergonomic controller features two plug-in jacks and a four-button interface that allows easy, independent control of two vibrators with 7 speeds of vibration each when the controller is paired with a compatible bullet vibrator (sold separately).

The controller is powered by three AA batteries (not included), and is compatible with all Sterling Collection vibrator attachments.
