Frequently Asked Questions
How does Firefly work?
Firefly uses small electrical pulses to stimulate the peroneal nerve (a nerve in your leg). This increases full-body blood flow. That means more fresh blood and oxygen to reduce lactic acid and soreness, eliminate toxins, and keep muscles flexible.
When and how long should I wear the Firefly devices?
Recommended usage will optimise recovery so you can train harder and perform better. Firefly Recovery is used for warm up (30-60 minutes) post workout recovery (1-4 hours) and travel (duration of travel).
Should I use Firefly during training or working out?
No, it is not recommended to use Firefly during training or a workout. However, as Firefly is a portable device, it can be used when walking, stretching or on-the-go.
Can I use Firefly for upper body recovery?
Absolutely. Since Firefly increases blood flow throughout your entire body, it always functions as a full-body recovery device.
Do I need a knee strap?
We recommend getting the Knee Straps.
The Knee Strap keeps Firefly securely in place whether you are resting or in motion. Additionally, as the gel-based backing on Firefly devices may become less adhesive after multiple uses, the knee strap will help to ensure proper stimulation from the device.
You can get the knee straps here.
How do I use Firefly?
Firefly Recovery is used for warm up (30-60 minutes), post workout recovery (2-4 hours), and travel (duration of travel).
Simply apply Firefly to the correct location on your peroneal nerve and turn the device on.

How long does Firefly last?
When used as recommended, the Firefly device has a 30 hour battery life. The number of uses will depend on the length of each recovery session (average session is 1-4 hours). Afterwards, the battery is not rechargeable, it can be removed and recycled like any household battery.
Is the Firefly device painful to use?
The Firefly device should not be painful. You will feel muscles in the lower leg contract every second, which causes your foot to twitch (Firefly flutter). It may take a few moments to adjust to the sensation, but the movement is critical to increasing blood flow and recovery. if the sensation is too strong, decrease the level.
How does the Firefly device differ from muscle stim?
The Firefly is a modified NMES that stimulates a nerve vs. a muscle, it is not a muscle stim or TENS unit. Stimulating the peroneal nerve causes muscles to contract and to increase blood flow. Stimulating a muscle (with traditional NMES) for extended periods of time can cause muscle fatigue. The Firefly safely avoids muscle fatigue that can be caused by TENS.
Who should not use the Firefly device?
Individuals with pacemakers and recently diagnosed DVT should not use the Firefly. Instructions accompany the device and offer a full list of contraindications, warnings and precautions.
