Questions & Answers
Recommended usage will optimize 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).
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.
Knee Straps keep firefly devices comfortably and securely in place, especially when you are in motion. As the gel-based backing on the devices may become less adhesive after multiple uses, the knee strap will help to ensure proper stimulation from the device.
When used as recommended, the device has an estimated battery life of 30 hours. The number of uses will depend upon the length of each recovery session.
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.
Press and hold down the (+) button for 1-second to turn the device ON.

Press and hold down the (-) button for 3-seconds to turn OFF your device.

We suggest using the firefly for the duration of travel to promote blood flow and avoid tired legs. The firefly device can safely be worn or carried through TSA security.
The device is specifically meant to be applied on the peroneal nerve to increase systemic blood flow. We have not researched our technology on other nerves in the body.
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.

The firefly looks like a muscle stim but is similar to pneumatic compression. Both modalities increase blood flow. The firefly is unique as it moves 3X more blood, is fully portable, and mobile. This allows for on-the-go recovery anywhere, anytime. Click the button below for a modality comparison.
It is safe to sleep with the devices on. However, quality sleep is essential for optimal recovery; if the devices are disruptive to your sleep, lower the settings or turn them off.
No. The firefly device is not designed to be used in water as it is not waterproof.
At the correct level, you should see an outward movement of the foot (the firefly "flutter"). If you only see muscle twitches in the lower leg but not the foot, increase the level by pressing the (+) button or adjust the device placement. It is optimal to wear the firefly at the lowest setting that delivers a “flutter”.
Individuals with pacemakers and recently diagnosed DVT should not use the firefly. See the instructions that accompany the device for a full list of contraindications, warnings and precautions. Please see our technical specifications.
The Firefly device is reusable during the 30-hour life of the battery and can be used for multiple recovery sessions. Afterwards, the battery can be removed and recycled like any household battery but cannot be replaced. The Firefly device is not rechargeable at this time. We are looking at ways to extend the life of the product and make Firefly rechargeable.
Yes. Technical specifications are available using the button below.
It is best to store/transport your Firefly in cool, dry conditions. If possible, avoid leaving in a hot car or other extremely hot or humid location to keep the hydrogel in optimal performance condition.
