Common Questions
Frequently asked questions.
Firefly is portable, wire-free recovery you can wear anywhere — especially on long travel days when you're sitting for hours. It uses wearable NMES to stimulate the peroneal nerve and create gentle muscle pumps that boost blood flow up to 400%. That extra circulation supports recovery, helps ease post-workout soreness, and keeps your legs feeling fresher so you can train harder, travel easier, and stay ready for what's next. FDA-cleared and designed to fit seamlessly into your routine.
We suggest using the Firefly for the duration of travel to promote blood flow and avoid tired legs. The Firefly device can safely be worn or carried through TSA security.
At the correct level, you should see an outward movement of the foot (the Firefly "flutter"). If you only see muscle twitches in the lower leg but not the foot, increase the level by pressing the (+) button or adjust the device placement. It is optimal to wear the Firefly at the lowest setting that delivers a "flutter".
Press and hold down the (+) button for 1 second to turn the device ON. Press and hold down the (-) button for 3 seconds to turn OFF your device.
Recommended usage will optimize recovery so you can train harder and perform better. Firefly Recovery is used for warm up (30-60 minutes), post workout recovery (1-4 hours) and travel (duration of travel).

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing.
He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.

Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.
