Don’t trust the delivery date!

I do like this however, I think 4 patches for 25.00 is expensive. I like seeing how much I sweat during runs, hot walks and weight training. With these single use it’s expensive. I wish they could be used once a day for all workouts

Easy to navigate. Great product.

Really easy to use, fun product, and great customer service with quick responses. Definitely recommend!

Using the Nix has been eye opening for me, I had no idea how much sodium etc. I was actually losing. Once I made the adjustments to what I took on my long runs and post run I have felt so much better. The investment was definitely worth it.

The Nix Sensor has changed my running life. I have had trouble gauging electrolytes for years. Nix allows me to have live feedback on my electrolyte loss so I can replenish and prevent hyponatremia. Thanks to Nix, I can run ultras on hot days again. Picture is me at my last ultra, the Centurion 33 hour. Thanks Nix!

I no longer struggle with cramps late in marathon races . My training has improved as well. Now I can plan ahead for workout and race days , as well as make sure I'm optimizing my recovery as efficiently and effectively as possible.

Nix Biosensor has been key for me as someone prone to dehydration headaches. I always knew I was a heavier sweater and ended up with a ton more salt residue than my training partners, but was truly guessing at how to support this. I now know exactly how to dial this in and make sure I am getting what I need to train and feel my best!

As I stepped into ultra running, it became very apparent how crucial proper hydration is. For me, using the Nix monitor has been less about relying on absolute, lab-grade numbers and more about building better habits. The data has served as a valuable baseline, educating me to be far more conscious of my body's fluid needs. The real benefit has been the real-time reminders - they prompt me to stay on top of my hydration strategy and help me actively manage my races differently.

So far so good. Only two mtb rides in with the sensor. I fight cramping on big rides and I've been trying to find out what my issues may be. I found that I have not been consuming enough electrolytes for the entire ride. Just another piece of information that could be helpful.

Great tool; would have been 5 star if I didn't need to run phone app at the same time when running

Great overall, but having to run the phone app at the same time is inconvenient

Still waiting for it. .

They work really well. Very happy with this product.

Easy to work with and fast shipping

Hard to get a hold of since support is limited to email

Lovin’ it

The data it provides is great, it gives you a good baseline into your hydration. The app sucks.

Very helpful to realize my water and salt lose in Arizona. Because of the dry climate I tend to under estimate my lose during my long bike rides. Reminds me to keep up on the lose and prevent dehydration.

Excellent as always
