I have had a Frontier X for several years, and recently upgraded to a Frontier X2 so I have a second one for travelling. This is a great product. In particular I find the "heart strain" metric very useful. I use this to push myself harder when I'm feeling healthy, particularly when I was running regularly. The Frontier X's heart strain reading was was my main metric during my recovery from long covid over 7 months. I learned that if I pushed myself too hard, I could get a couple of weird symptoms, but as long as I kept my heart strain below a particular threshold (0.08 in my case), I could safely exercise. Without this, I likely would have been afraid to exercise at all, which would have prolonged the recovery period. Not a lot of difference between the Frontier X and the Frontier X2. A bit faster data transfer, but the same reliable information, presented in an easy to read format. I rely on my Frontier X, and it's been a great product. I highly recommend this.

Purchased the device on a whim, I have used other heart rate devices before but none with real time ECG. Thus far I have been super impressed with the fidelity of the data as a medical professional who works with ECG I have found it very interesting to go through my workouts and looks at how my data changes depending on the conditions. I have had no issues and been extremely happy with the purchse

This was a great experience. First the person spoke flawless English. She is also from the same town that I grew up in. Quite experienced. Solved my problem immediately. Also offered to send me the USB cover that I lost. I think that this company is going to go places. So far I have spoke with Abhimanyu, Peter and now Sana from the company and all of them are extremely helpful and courteous. Nadir Ali, MD Cardiologist based in Houston, Texas

Great device! Connected immediately. No tech head scratching involved. But what really made the difference was the product support. They are there for you and they know their product. Very happy 😃

I love my Frontier monitor most of the time. But it easily becomes detached during even a light workout. I spent a few hours yesterday searching for it after it became detached while doing some chores around the yard. It's now really banged up with a lot of scratches. Also, the micro-usb charging process is very vulnerable to damage from dirt, sweat, or water. The flimsy plastic cap is easily lost when it's removed for charging. 99.9999% of the engineering effort went into the electronics and the remainder went into making sure the unit stays attached and charged. My advice, wait for the next version. Maybe FF will fix these glaring design issues. In the meantime, I've got a banged up unit that I'll sell - cheap.

I love having access to my heart health, especially knowing heart disease does exist in my family history. The onboarding call is so cool to help answer any questions and understand how to maximize the benefits of the product. I also love the recommendations on how to improve on previous workouts. $500 isn't cheap, but I feel it's well worth the price, highly recommend.

I have owned this monitor for about a year and nothing out gives the data fourth frontier does. The information provided is good intel for your cardiologist and allows you to closely monitor how your heart is functioning. Great product for healthspan!

Helpful, great support and medical usefulness remarkable

The set up was very straightforward The quality of the data excellent along with the customer support

I've been using Frontier x2 for a couple of months now. Been using it in all types of activities... even during sleep. Juat an awesome device to have. It helps guide me on how to approach my daily training. Online staff is quick to respond to any inquiries. Very helpful indeed.
