These things work great for an older athlete seeking quicker recovery. However, I am extremely disappointed that the batteries are not rechargeable or replaceable. This is clearly an expensive inconvenience which seeks to sell replacements.

Really liking my Fireflys! Great passive recovery system that I can take with me anywhere. I've ben recommending these to all of my clients now

As a college athlete I find it really hard to fit recovery into my schedule because of how busy it is. The fireflys make it so easy to really prioritize my recovery without it being a hassle to use. When using these in season it was so essential to keep my shin splints from flaring up by keeping the inflammation in my legs down. I was able to train harder while still being able to perform my best during games.

I enjoyed the ease of use and quick recovery after standing for many hours.

My Garmin watch tells me the needed hours for recovery after tough track intervals and cycling activities. Firefly has reduced my recovery needs by one full day.

I’m 55 and very active with weights and peloton for many years. I also have edema unfortunately so I gave firefly a shot and so far very impressed. My recovery with squats and cycling is drastically faster but it takes away my edema pains almost instantly. I can’t wait to use these when i saddle hunt this year thanks firefly !

I purchased the Firefly specifically for a golf trip where the courses were walk-only—no carts allowed. Walking 36 holes a day can really take a toll, but the Firefly made a huge difference. It significantly helped with recovery, and I noticed that I was able to play at my full potential every day. I’m really glad I brought it along. Thank you for an outstanding product!

Great product, no more sore legs after Leg day. Great for jet leg as well, highly recommend this product!

They seem to be helping me recover better. I've been doing them for 1-2 hours after I run that day in the evening. I seem to be sleeping with less achey legs. I still have soreness the next day but not as bad as it was before. It's definitely a great tool to have. I only wish they offered some sort of rechargeable device or atleast the ability to purchase replaceable batteries that work at a lower cost. $50 a month is a bit much. Because of this I am not using it every day trying to extend the life before I have to purchase another one (if I decide).

Love my firefly’s!!! Really great for long haul flights and keeping the circulation in my legs optimal.

I love the flexibility of the device. As an avid endurance athlete and dad of two toddlers I’m always on the go. Compression boots force me to be immobile, Theraguns are too loud at times, so the FireFly allows me to remain flexible without interruption of my workday and daily activities. I’ve noticed my legs have felt recharged going into the next session and found almost immediate benefits.

Much easier than other products on the market for avoiding dead legs

I am presently in Physical Therapy due to a tear in my quadriceps. I thought Firefly would be a wonderful adjunct to PT and it has been. My expectations were low compared to the elaborate equipment in my therapists office. I was wrong. I can use Firefly and get relief and recovery whenever and where I need it,

Has been great for relieving knee pain!

Training for a half marathon and using Firefly for my recovery has been a GAME changer!!

I was getting ready for a long trip to Europe and didn't want to miss anything! I researched and found firefly weekender and decided to give it a try. They worked great and I didn't skip a beat while traveling and returning home.

I opened and immediately tried them on. I have used muscle stum before but this was different. I felt increase energy and more awake. I have also given my second pair to an athlete who runs the 100 triple and 200 he is showing much better recovery inbetween races. I am a strength coach for a high school and help with track and field in particular.

I will confess that my confidence level was pretty limited regarding the benefits of the Firefly Recovery Devices. However, I found that I loved them. But my next concern was keeping them in place- especially as the adhesive backing began to be less effective. It turns out the Firefly Recovery Knee Straps are the perfect complement and perform admirably. I have found a worthwhile product that doesn’t break the bank. I’m quite pleased.

These are so convenient for recovery, I can just put them on and go about my normal daily activities and still be recovering at the same time!

Love how it's portable. Once firefly is on, you can go on as normal. I've found firefly is great for pre game/pre-workout. This recovery device is a game changer.

I found this very helpful. I look forward to them making this rechargeable.

They do what they are advertised to do.

What a great product. Easy to use and definitely works. Gone are the days”tired legs” after long rides and, best of all, I’m not stuck at home while I recover! This is a must buy.

They worked! Why I fly, I get a terrible pain that starts at the top of my foot at my big-toe all the way up my calf to the left side. Firefly fix that!! Had a 3hr 45min flight and not pain!!!

I would give it 5-stars, except my travel days were long (10 and12 hours each) due to airline delays/cancellations, etc., and the 'sticky' back became a bit gelatinous. They are not easy to put on in cramped spaces.

I'll definitely use these again.

JFK-LAX flight (on the plane for over 7 hrs) and the first time I haven’t had cankles after a long haul flight in years! I was skeptical, but I think Firefly is a winner.
