This is my second order and I gave half my first order to a friend to try. Even when my legs aren't overly tired, I use it to alleviate possible cramps.

I’ve always played sports and kept myself active, but recovery post competition/training was always a challenge. I’ve recently started training for a half marathon so I’m running longer than I ever have. Needless to say, my legs have been very sore and especially after an Achilles rupture. I’ve been using these fireflies for recovery and they are spectacular. My legs feel recovered within a couple hours of wearing the fireflies. I really wish I knew about these years ago-they would have come in handy after soccer tournaments, beach volleyball games, Spartan races, and cross fit competitions. I’m so glad I have them now to take on new adventures!

I started using the Firefly Recovery devices last year during my freshman season as a Division 1 gymnast, and it has completely changed the recovery game for me! I was struggling with some tendinitis in my lower legs, and the devices definitely helped with my pain and soreness. I highly recommend using the Firefly devices!!

Firefly has been instrumental in rehabbing my ankle after a second-degree inversion sprain. The peroneal muscles on the outside of the calf & foot, and nearby ligaments around the outside ankle bone bore the brunt of the injury, and are responding exceptionally well to the stimulation that Firefly provides, reducing soreness and restoring mobility. Also, the overall boost of circulation (blood, lymph, interstitial fluids) throughout the entire body had the added benefit of “awakening” the fascial highways/networks, resulting in un-sticking some longtime adhesions I had around the SI joint. This was totally unexpected! I don’t understand the mechanism, but it is a significant, far-reaching phenomena that pairs well with Somatic awareness and targeted muscle isolation exercises. It’s an exciting discovery for me, and I’ve relayed my positive experience to those in my immediate circle: ballet dancers, ice skaters, and bodyworkers.

I’ve been using Firefly Recovery after training, and it’s been a game changer. Super easy to use, totally portable, and I can wear it while doing other things. I’ve felt a big difference in how quickly my legs recover, I have less soreness and more energy for my next session. Highly recommend it to any athlete looking to take their recovery to the next level!

Firefly is a super easy recovery tool that has helped me maximize my recovery on the go. Highly recommend.

I’ve been an acupuncturist for 26 years. Have gotten into Electroacupuncture more in the last 8 years with astounding effects. I saw Firefly on social media and where I saw placement and the use of the impulse piqued my interest. Plus I see many athletes as well as world travelers. I had to try it. When I received the product I actually just had a silly but pretty jarring fall on my knee and jammed it which it affected the bend and my hip. I then had to fly across country. Using firefly not only helped me walk through airports with ease, I feel like it aided in treating it. The placement of the Firefly is loosely on the acupoint GB34 which is an influential point of joints/sinew. It made sense to use it for the jammed knee and glad I did. Now i recommend this for my patients… even those healing from knee and hip surgeries including replacement for recovery from swelling and pain. I believe it helps between treatments to increase the effects of the body’s amazing ability to heal even more.

Currently training for my first marathon and my firefly devices have drastically improved my recovery time between gruelling long runs! Would buy over and over

I am a college volleyball player and I am almost out of the trenches of preseason! I get bad shin splints and I just have tired legs and firefly has helped rejuvenate my legs so much. Many of my teammates have tried using them and loved it too! I am very grateful to be working with firefly, excited to see how this brand grows to help more and more people!

My day starts with a good workout but after lunch I was having fatigue and brain fog from Mast Cell Activation disease. The firefly definitely helps to get me through the afternoons. Grateful my doctor sugggested them.

Didn’t know what to expect but in one use on a London to New York flight I couldn’t believe how light my legs felt when I landed!

Can’t wait to use them again on my next flight, these are a game changer!

As a chiropractor who spends long hours on my feet and constantly uses my body to treat patients, recovery is non-negotiable for me. The Firefly Recovery device has been a game changer. It’s easy to use, portable, and I can throw it on right after work or even while I’m getting things done at home. I’ve noticed less soreness in my legs, faster recovery after workouts, and overall better energy throughout the week. It’s rare to find something that fits seamlessly into a busy lifestyle and actually delivers real results. Highly recommend it for anyone who values their performance, health, and longevity.

I really didn't know how this would work, but it is BEYOND BELIEF! I recommend this highly. and have already sent several friends to this website. Thank you for a killer product, Firefly!!!!!!

Wish I had these with me at the Olympic Games when I was competing, they are such a great tool for recovery, and as absolute must when traveling

We are Seven summiters and used Firefly device to recover faster at Mt.Aconcagua, Mt.Elbrus, and Mt.Fuji. It is so light and battery lasts 30 hours and can work even in cold harsh condiitions at high altitude. From flying in longer hours to climbing above 22,000 feets, we trust our Firefly.

Firefly blew me away. The recovery boost is real — my legs felt lighter and way less sore after long training sessions. Super easy to use, comfortable, and they make a huge difference. Definitely a game changer for me!!!

As a D1 track and field athlete who works full time AND has a puppy in addition to my studies & sport, it is hard for me to find time to recover... However, firefly has changed the game. I can recover during work, travel and relaxation time with almost no effort. Drastically helped.

My biggest frustration has been heavy DOMS, like crippling muscle soreness after sessions. I do a pretty niche extreme sport called tricking that demands a lot from my body, and I need to perform a lot of reps in order to progress. Recovery is essential and I've tried everything you can think of, but these have been my favorite and most effective. Nutrition, sleep and blood flow from firefly. Lets me focus on my sessions and stretching. I love how they're passive, meaning I don't have to "try" or use any mental energy even if I were to use a foam roller or massage gun, it still takes some effort/awareness since you're massaging yourself there's a technique to it, where these just blend into the background while I'm chillin, I love them.

I use them for 30-60min warmup, and sometimes 4+ hours in the afternoon/evening and as much as possible if I'm extra sore. I've noticed a huge improvement in my sleep too, I sleep DEEP. Pair 30-60min of firefly before bed with proper nutrition (+magnesium) and you'll feel great. If I know I'm going to be sitting for a while, I always put these on.

It's worth noting that every time I change positions, walk or extend/bend my legs I have to adjust the level and for some reason my left leg needs one level higher than my right. I always use the minimum level for the foot twitch and never had to go above level 3. Sometimes it's hard to tell which level to use when walking, since your foot doesn't twitch up when walking, I kinda have to lift my foot for a second and see if it's doing the flutter. I usually just keep it at level 2 or 3 when walking for me and I think that feels right.

A few weeks ago I reached out about your product firefly. I was desperate to get them in time for my trip to Europe. You and your team were so kind and you got the order expedited so I would receive them just 2 days before my flight. I want to say “ thank you from the bottom of my heart!! These things made my trip! Otherwise I would not have been able to make it through the airport when I arrived from the 9 hour plane ride. I also used them on the ground to recover from a day of sightseeing and still had enough power left to wear them on the flight back home. All I can say is this is the real deal and the most valuable thing I took with me on the trip! Everyone should own these things!!!

I'm a 40 year old former athlete training for my first marathon. I've been derailed in the past with these sorts of things with soft tissue strains, and just recently I suffered an achilles strain that threatened to do it all over again. Thanks to using firefly repeatedly, I only needed to take a few days off, and honest to goodness feel good as new 5 days later (for something that, in the past, we're talking about weeks). I'm beyond impressed, and also grateful!

I’ve used this product after every training session through the week. My recovery process speed is insane. I love these.

Fantastic results time and time again.

I use these every time I do a long run or leg workout, and I wake up without pain in my legs and ready to workout the next day!

As a track athlete, recovery and blood flow are everything and the Firefly device has been a game changer for both. It’s super easy to use, lightweight, and absolutely perfect for travel. I love how confident I feel knowing I can recover on the go, whether I’m on the bus to a meet or flying out for a competition.

That said, I do wish the adhesive was better. Even though it comes with straps to keep it in place after the stickiness wears off, it sometimes still doesn’t hold firm enough to properly activate the nerve. I often have to stay in a very specific position for it to work effectively.

Overall, a great product I’d definitely recommend to other athletes serious about their recovery.

Such a good idea, super discreet and very beneficial for long flights especially after a tough workout...will definitely be back for more!
