Quick background--I had been having some irregular heart beats during exercise and was looking for a way to investigate what was going on. Found the Fourth Frontier X2 online. I use it every time I workout now and also when I sleep. I have gotten a lot of great insight into my heart health and am quite happy with the product. The X2 is helping me and my doctor manage my newly diagnosed Atrial Fibrillation.
--The Heart Strain indicator is quite helpful. I have had the "buzz" on the device go off a couple of times. It tells me to lower my workout intensity.
--The heart rate is accurate--as compared with my Polar H10 strap and several manual counts.
--Breath rate is helpful information not supplied by other heart rate devices
--The HRV reading is helpful and compares very close to my Oura ring.
--Sleep data is impressive and compares very close to the Oura ring.
--The X2 could easily take the place of the Polar H10 strap and Oura ring.
--The App is intuitive and provides a lot of useful information.
--I love that the app will generate a PDF of the ECG that can be emailed to your cardiologist/doctor.
--I love that the X2 is charged via USB instead of a battery like the H10.
--Battery life is impressive--I have worn it all night while sleeping followed by 3 hours of use during exercise and have not gone below 70% charge. I once wore it for 18 hours and only got to 60% charge. The X2 charges in just a few minutes-much faster than my Apple watch.
--My cardiologist was enthusiastic about my use of the X2. He found the ECG data useful--especially because he could see what was happening during a specific activity. I had worn a 2 week monitor through him--but of course I didn't have any weird beats until after I turned in his device. The X2 ECG is helping to guide my treatment.
For those of us who are aging-athletes with many decades of ultra-endurance training and competition and consequent cardiovascular issues, the metrics FF X2 provides are indispensable to be able to see in real-time. For me, those data, when combined with real-time measurement of muscle oxygen and watt output allow me to calibrate my work to enhance safety and fitness.
To my knowledge, there are no other wearable monitors at the price point of the X2 and Premium subscription that can provide such data.
I suffered from heart failure a few months ago. The Frontier X2 device has been an absolute game changer. I was able to go back to exercising because of being able to measure ST Depressions on the move and to set alerts that make sure that I'm safe. This device has let me live life normally again and for that I'm thankful. The ECG livestream feature is a god send because it lets me share my live ECG with my cardiologist.
