How to wear the Firefly Knee Strap

Firefly is placed directly over the fibular head (round bone below joint line of the knee). Be careful not to impinge on the crease of the knee.  This knee strap promotes ample security to the device and allowing it to stay fixed in a more reliable position on the leg.  Great for use on longer travel or overnight during normal sleep cycles.

If you haven't heard about the Firefly device you can read about it below:

We’ve all heard the Moto: no pain no gain. The emphasis in training used to be to add more mileage or increase intensity.

In recent years we’ve learned the value of recovery. If your training load is exceeding your ability to properly recovery it usually results is overreaching followed by overtraining, injury, illness and more.

If you’ve ever been to a physical therapist, you’ve probably experienced electrical muscle stimulation. These devices can be quite expensive and be somewhat cumbersome with all of the wires and attachments. However, their efficacy has long been validated by Major league teams, NCAA teams, and just about every medical practitioner on the planet.

Meet Firefly… the latest innovation in sports recovery. The Firefly is an electric sports recovery device that stimulates the peroneal nerve on the knee to elicit a muscle contraction in the calf that stimulates blood flow.

The benefits are two-fold. By circulating blood to your heart faster you are going to get more oxygenation in your blood. Obviously, this is ideal for overall performance and recovery. Secondly, you are getting an increase in lower extremity microcirculation by 400%.

If your competition schedule requires heavy travel, you are trying to expedite recovery from an injury, or just performed a heavy training block Firefly is your secret weapon to faster recovery.

Recent research papers validate Firefly as a device to increase blood flow. However, the real benefits are validated when using diagnostic ultrasound. You can see the reduction in inflammation first hand as blood goes rushing through your lower extremities.

How to use the device

The firefly operates at 7 different intensity levels. Athletes typically wear from 2 - 4 hours. However, many athletes are wearing for the duration of overseas flights, or overnight as an aid from injury.

The BEST water bottle on the market!
Color: Denim, Size: 32 Ounces
I am in love with this water bottle! I take it everywhere with me, and I love that it has a built-in straw. The color is perfect as well. It motivates me to get my water intake in, and it helps me meet my fitness goals. It is easily washed in the dishwasher, and I don't have to worry about it breaking. It keeps the temperature of my water perfect- whether I add ice or not. It is sturdy but not too heavy.

This mattress cover is great! Well worth your money
Size: Twin XL, Style: 1 Green
This mattress cover is so comfortable. I am scheduled for back surgery in a week so when I find something I can sleep on and call it comfortable you best believe it is! It fits well, it’s pretty and it’s very fluffy. Seems to be made very well. I am confident that I’ll get a lot of wear out of it.

Very Comfortable - Love this!
Size: Full, Style: 1 Green
So far, so good! I am going on my first night trying this mattress topper out. It feels very comfortable and definitely is fluffy, but not too fluffy. I did not "fluff it out" or put it in the dryer to fluff it out quicker, so perhaps it still needs some time to fluff out some more. It was very easy to place on my mattress. I didn't have to fight with it as I normally would when fitting a sheet to my mattress. I love that it stretches over the sides of the mattress to hold it in place. The bamboo truly gives a cooler effect, which will be very helpful in the summer time. I used a microfiber mattress topper prior to ordering this topper. So far, the comparison is that this one appears to be well made and durable, unlike the microfiber one I had before that changes color as it gets old and dirty and is impossible to clean. The old one actually ripped and would constantly move. I am excited to see how well this one holds up over time. I had no trouble placing a fitted sheet over this mattress topper. I love that this one is machine washable and is able to be placed in the drier. It feels very nice on my legs and is comfortable for my back as well. The padding doesn't feel thick or bulky but definitely adds a softness that is super comfortable. It's too soon to tell if it's water resistant as I haven't tested that feature out yet. I placed it over an old, springy mattress and it truly feels like I have a whole new mattress. Time will tell how well this product does the job and I will update this review if I end up having any issues with it.

IT'S LIKE SLEEPING ON A CLOUD!!
Size: King, Style: 3 White
OMG I AM SLEEPING ON A CLOUD!!! THIS! Life changing!!! We went on a Royal cruise and asked for a mattress topper. When we got home I just had to find one for our bed because I sometimes find it to be too hard. Along comes THIS topper! The very first night it was on the bed I slept the entire night without tossing / turning which I NEVER do! Along with every night since! It fits perfectly on our King bed and no issues with the sheets. It does have a chemical smell when you first open the bag - but I put it in the dryer on air only and the smell dissipated in about 20 minutes. No smell at all by the time we went to bed. it appears to be washable. It's very soft so there isn't really any back support. Just adds comfort to the bed. It is bamboo and really as soft as a cloud! Even my husband got into bed the first night and said AHHHHHHH SOFFT! Super bright white appearance. Not sure if it is water resistant. We added it on top of the mattress protector without any issues. All of the FOAM mattress toppers are terrible! They end up getting really heavy, you can't wash them, they get lumpy, and you end up sweating like crazy on them! THIS - nice and cool! And my hubby runs hot!! I call him the heat miser! No issues! We're both very very pleased!! If you're even thinking about purchasing - ADD IT TO YOUR CART NOW!

Not like the pictures but well worth the money
Size: Queen, Style: 1 Green
4 stars because it is not nearly as padded as the descriptions and images make it seem. The filling flattens easily and doesn’t provide any support. That being said it does make my bed more comfortable and soft and has improved my sleep quality. I have a 12 in soft/medium firm memory foam mattress that was wonderful for the last +2 years till my back surgery ~6 months ago. Since then my joints ached when trying to sleep and when waking, my back would be all out of place and achey, and I was untested. Since buying this topper these issues have improved by 80% or more. It is a great addition to my bed and I don’t regret buying it.
