How Does it Work? 
 
Firefly delivers electrical pulses to stimulate the peroneal nerve in your leg, triggering muscle contractions that boost blood flow. This enhanced circulation speeds up the body's natural recovery process, helping to reduce muscle soreness and get you back to your active routine quicker.
 
Each Firefly device delivers 30 hours of recovery treatment (suggested recovery time of 1-4 hours based on training intensity).
Most users prefer to use Firefly with knee straps. The knee straps help to keep Firefly in the optimal position for maximum benefit.
The battery is not replaceable / rechargeable.
