Adjustable Timer & Intensity: The timer allows you to set a time of between 10-60 minutes, with the default set to 20 minutes. Twenty levels of adjustable intensity mean you’ll easily find one that suits your needs.
Dual Output Design for Multi-person Use: Simultaneous dual output design allows use by two persons or for use in two different body areas.

A battery level indicator reminds you when charging is needed.
