Suggested wear time is 2 to 4 hours per session, with 4 hours to maximize recovery. Recommended usage will optimize recovery and get you ready faster for your next training session, game, or race.
Post-workout recovery During in flight travel When sitting for long periods of time
No, this is a post-workout recovery product. 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 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.
When used as recommended, the device has an estimated battery life of 24 hours. Each firefly device provides 6-12 recovery sessions, depending on the length of each recovery session (suggested 2-4 hours).
Using the firefly device should not be painful when used at the correct level. However, 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 this sensation, but this movement is critical to increasing blood flow and recovery. If the sensation is too strong, you can decrease the level.
Press and hold down the (-) button for 3-seconds to turn off your device.
The T2 is a new and improved version of the original firefly device. It is more intuitive to use, more comfortable to wear with a longer, more pliable strap, and has a more consistent battery life.
We suggest using the firefly for the length of travel to promote blood flow during flight.
The device is specifically meant to be applied on the peroneal nerve to increase blood flow from the lower extremities to the heart (systemic blood flow). firefly increases lower extremity microcirculatory blood flow by 400%. We have not researched our technology on other nerves in the body to increase blood flow.
The firefly is a modified NMES signal that stimulates a nerve instead of a muscle. firefly is not a muscle stim or TENS unit. By stimulating the peroneal nerve specifically, firefly causes muscles to pump and therefore increase blood flow. Stimulating a muscle for extended periods of time can cause muscle fatigue. The device safely avoids muscle fatigue by stimulating a nerve.
firefly is a unique, portable device that increases blood flow and improves recovery. While other technology such as pneumatic compression sleeves can increase blood flow, firefly is portable which allows for on-the-go, enhanced recovery – anywhere, anytime.
There is no detrimental effect to sleeping with the devices on. However, as quality sleep is essential for optimal recovery, if the devices are disruptive to your sleep, you should lower the settings or turn off the devices completely.
No. The firefly device is not designed to be used in the shower as it is not waterproof.
At the correct level, you should see a discernible outward movement of the foot (the firefly "flutter"). If you only see muscle twitches or movement in the lower leg and not the foot, then you should increase the level by pressing the (+) button or adjust the placement of the device.
Individuals with pacemakers and recently diagnosed DVT should not use firefly. See the instructions that accompany the device for a full list of contraindications, warnings and precautions.
In the unlikely event that you are not satisfied with your purchase, you may return your firefly devices within thirty (30) days of the delivery date. All returns and exchanges are subject to the conditions in our Return Policy
