Best active recovery device out there, in all aspects of sports this is the best of the best, helps you recover between workout sessions making your body replenished and ready to go for the next activity!

I've been using Firefly with my athletes and it has been a life changer

As someone living with Postural Orthostatic Tachycardia Syndrome (POTS) and complex chronic illness, I am highly selective about the tools I use and recommend. Firefly has become one of the few recovery devices I consider genuinely supportive rather than gimmicky.

Firefly uses targeted neuromuscular stimulation to activate the peroneal nerve, supporting venous return and circulation in the lower limbs. For individuals with POTS, this mechanism is particularly relevant, as blood pooling in the legs is a core contributor to symptoms such as dizziness, tachycardia, fatigue, and presyncope.

From a lived-experience perspective, I have found Firefly most beneficial:
• During prolonged sitting or bed rest
• Post-activity when circulatory fatigue is prominent
• On days where compression alone is insufficient
• As a non-pharmacological adjunct to symptom management

What differentiates Firefly is its simplicity, portability, and passive nature. On days where energy, coordination, or executive function are limited, it allows symptom support without additional cognitive or physical load.

From a clinical lens (as a nurse with postgraduate mental health training), Firefly aligns well with evidence-informed autonomic management principles, including:
• Enhancing peripheral circulation
• Reducing orthostatic stress
• Supporting recovery without overstimulation

Importantly, Firefly is not positioned as a cure, but as a practical tool within a broader management plan that may include hydration, electrolytes, compression, pacing, and medical oversight.

I recommend Firefly particularly for people with:
• POTS or orthostatic intolerance
• Hypermobility-related autonomic dysfunction
• Chronic fatigue with circulatory symptoms
• Limited tolerance to compression garments

As the founder of The Recovery Toolkit, my focus is on accessible, evidence-aligned supports that respect the realities of chronic illness. Firefly meets that standard and is a device I use personally and feel confident discussing transparently with my community.

Firefly has become my favourite recovery option the last few months since trying it. Playing professional tennis and constantly travelling, firefly has been a game changer. Being so easy to use while still moving is so convenient, especially during flying. I feel so much fresher after flying which makes it easier to get on court and training sooner! Would recommend to everyone!

I recently traveled for an almost 9 hour flight and used firefly and when I arrived at my destination, I felt like a million bucks. My legs and feet were not swollen nor was in pain throughout the flight. Highly recommend using this device if you have a hard time with air travel.

Firefly’s become a part of my weekly routine as a distance runner. They’re great for recovering between double sessions, getting ready for a race, and keeping my legs fresh during travel. They’ve been a game changer for me; 10/10 recommend.

I’ve been using Firefly for my competitions, pre-practice prep, recovery, and it never fails to get me extra prepared. As a sprinter, I highly recommend.

The Firefly Recovery System has been a game-changer for me. After taking ground balls and swinging, my legs are usually worn out and heavy but using Firefly made them feel noticeably refreshed and ready to go again. I could feel the difference almost immediately in how loose and energized my legs were. I’m especially excited to use it on my upcoming flight to Florida to help keep my legs awake and prevent that stiff, tired feeling from sitting too long. If you train hard or travel often, this is a must-have for recovery.

Bought these for my trip this past April to El Camino Spain. I would have to say they worked wonders. My legs never felt fatigued. Initially I was unsure about spending the amount of money, but I figured the one thing I needed to make sure I took good care of was my legs, otherwise I would not have been able to finish it.

Firefly is hands down the best recovery tool you can implement in your post run/ track workout rituals. It has helped my muscles recover faster so I can feel fresh so the next practice without letting my soreness worsen.

As a student athlete, finding time to recover properly is sometimes difficult. With firefy recovery, I was able to recover 3x faster wherever whenever. Perfect recovery device for those looking to recover on the go or something portable.

As a group fitness instructor, trainer, and presenter, and dancer my body is part of my work. I spend long hours on my feet teaching high impact classes, rehearsing, traveling, and showing up day after day with the responsibility to move well and lead from the front. Over time, that kind of volume creates real fatigue, especially in the lower legs, feet, and ankles.

I added the Firefly Recovery Device into my routine as a support tool, not a quick fix. I was not looking for an overnight solution, but for something that could help me recover more efficiently between long teaching days and rehearsal blocks.

What stood out to me was the gradual change. My lower legs felt less heavy at the end of the day. Foot and ankle fatigue did not carry over as strongly into the next session. I felt fresher going into back to back classes, which made a difference in how I moved, cued, and showed up. Instead of constantly feeling like I was managing soreness, I was able to focus on quality and consistency.

Firefly fits well into a longevity focused approach. It supports the work I am already doing to train smart, manage load, and respect recovery. It does not replace those habits. It reinforces them. Having that extra layer of support has helped me maintain better movement quality across consecutive days.

If you are an instructor, trainer, or presenter who relies on your body to do your job, this is a tool worth considering. Not as a shortcut, but as a practical way to support recovery so you can continue showing up with intention, confidence, and care for the long run.

As a collegiate runner this recovery device has helped me with quick turn around races and more. 10/10 would recommend to anyone on their feet all day everyday

I'm able to relax and even go to sleep without being bothered at all by the pulsing of the firefly. It makes my legs feel fresh after sitting down for hours.

I usually am disappointed with gadgets that claim to help with athletic performance or recovery and jet lag. Well I am a convert to firefly now. Just did Atlanta to Sydney and I have no jet lag. Seriously. I did sleep a bit on the plane but it was not restorative. I always fly economy and I am always always very very tired and jet lagged and feel horrible after I land. This was a game changer for me. I can’t wait to use them again on the return flights and I will be using them for all my travel needs.

I’ve been using it before my workouts and my legs have been feeling really fresh as well as after hard workouts. Really seeing the difference in speeding up recovery!

I genuinely love Firefly!! It’s one of those tools I can throw on after workouts or long days and let it do the work for me. I notice less heaviness in my legs and feel way more refreshed the next day. Super easy, low-effort, and perfect for recovery when I don’t want to add another step to my routine!!

👌

We are flying to Europe this summer and my restless legs were a concern for me. It is very bothersome, even on short flight and in the car. These are going to be so helpful, the stimulation these provide will truly help.

We purchased these for our son who had a 40 hr trip from JFK to LA to Sydney to Auckland NZ. He is playing for the USA U18 national 7’s rugby team, so we wanted him to arrive as fresh as possible. He said he slept 10 hrs on one flight and felt good when he arrived. He wore the firefly bands the entire time and turned them on while he was flying and still has battery life left and will use for recovery after he trains. Thank you Firefly!

Seriously helped recover in between volleyball games and kept my legs fresh just a quick light stretch and i was all set

This is an effective device for leg workout recovery. Way better than the inflatable legs.

Firefly has changed and enhanced my recovery from tennis 125%!!! It has also improved my driving experiences so I can get out of the car with no pain after long drives.

I have compression socks, normatech compressions, and massage guns but these make me feel more recovered after hard efforts by far. I don't use them for warm-ups, but for cool-downs on the couch, these are amazing to make my legs after cycling or lifting feel better. Also really good for travel, to keep the legs from feeling stagnant. Of course, rechargable would be better but these work wonders for people with busy training plans. I only use them after rides with intensity for an hour since I dont have money or time to use them more than 4-5hours a week.

Used my new Firefly travel package for the first time on my trip to Amsterdam. I've always had swelling in my leg and using Firefly made all the difference, no swelling this time. Give it a try!
