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!

I have used this product for years and it has revolutionized my recovery. Unlike the traditional compression boot, Firefly devices allow you to recover while completing other tasks and are easy to transport. It is an essential part of my recovery routine!

I have issues with patellar tendonitis and have found firefly to be very helpful in my recovery. I have been using it for a week and am seeing positive results in my pain levels going down.

As a college lax player, my knees have been through the toughest wear and tear. They hurt constantly. I’m now using this Firefly Recovery system daily and love it. My knees feel so much better! Thanks Firefly Recovery!

Firefly Recovery has been an absolute game-changer for my performance and recovery as a Division 1 distance runner. At this level, every training session counts, but so does every hour of recovery. Firefly allows me to train hard, bounce back faster, and show up ready for the next session with less soreness and fatigue.

My son is a runner and has noticed a huge improvement in his recovery since using firefly devices. He sometimes gets shin splints or DOMs after a tough workout and it has made a huge improvement in him feeling better the next day. We have been using for about 8 months (maybe 5-6 pairs) and will continue!

As a Division 1 golfer at the University of Hawai‘i, recovery is everything! Especially with the amount of travel we do for tournaments. Since incorporating Firefly Recovery into my routine, I’ve seen noticeable improvements in how I feel and perform. It helps me feel more energized, more prepared, and genuinely better both on and off the course. I use Firefly before workouts or rounds, during flights, and after tournaments. I genuinely will not travel without them, it’s made a huge difference in my recovery process.

I initially bought firefly for a long flight to and from Europe. My husband and I tried it and neither of us experienced any jet lag whatsoever.

We spend 5 weeks jeeping in the Colorado mountains late July through August. My left knee was really bothering me so I ordered more and used it under the knee that was bothersome. I kept it on for 30 hours, taking it off only to shower and reapplying the same unit until it ran out at about 30 hours. I have seen much better flexibility in that knee. I’m continuing to use the product through my trip.

If nothing else, it is a must travel unit for flights and long road trips.

I’ve been telling all my friends about it.

I had ligament surgery on my foot and recovery has been rough. I started using the firefly in my regiment to get the swelling down and it seems to be helping a lot. I also have a trip to Europe coming up and can’t wait to use it on the flight.

Firefly Recovery has been a game-changer for my recovery routine. The product is easy to use, lightweight and simple to throw in my bag, and incredibly effective at reducing soreness and speeding up muscle recovery. I’ve noticed a real difference in how quickly I bounce back after tough workouts/long weeks of training. Highly recommend it for athletes who take their recovery seriously!

This seemingly tiny device proves to be mighty in the work it does. After a 1 hour use my legs don’t necessarily feel good as new but they feel light, fresh, and ready to go.

As far as application it was a pretty simple process as long as your following instructions. A good rule of thumb was keeping the white tab on the front part of the leg.

As an athlete going into 2 a days for the next 3 weeks I can say I am happy to have another recovery tool that can keep me grinding.

As an athlete who spends a lot of time traveling, especially by plane, the Firefly Recovery device has been a game-changer for me. I love how small and lightweight it is—it easily fits into any of my bags, so I can take it anywhere without adding bulk to my luggage. Being able to recover while I’m on the move, whether it’s during a long flight or while waiting at the airport, has made my life so much easier. It’s quiet, discreet, and super easy to use, which means I can actually stick to my recovery routine no matter where I am. I’ve noticed my legs feel less heavy and sore after travel, and I’m ready to train or compete much faster.
