New to the Fourth Frontier and my experience has been fantastic so far. Very helpful with setup and live tech support. I'm very interested to speak with their health expert to discuss all the data that I am collecting and determine how to optimize my exercise programs.

Best training HR monitor ever with the best service
I am using the device since 2021. While I faced some annoying issues with FX1, the support team made everything possible to solve the problems, including changing the device if needed. Support is just close to perfect. I wish all companies provide this kind of service. Now I am using an FX2 and almost no issues. The device is amazing, all doctors and specialists who check its records get impressed. Really helpful to understand your training sessions, zones, performance, and heart response. I would like to mention that being a great device for people with heart problems, it is extremely useful for any sport person regardless heart health. For me it is a must to wear for each sport I practice, any session. If I forgot to charge it, I just postpone the session, I feel blind otherwise. I was also using the coaching program and was just amazing. I stopped for different reasons and cannot wait to sign up again. Just as a note to make it even better, you guys could include more data for each particular sport. However, with the new possibility to connect to other third parties devices could cover this, so you can use it together with any sport specific one. Also, just one thing I do not like, is the recharge slot cover, easy to be lost and not very confident to ensure watertightness.

Useful single lead ECG for heart rhythm monitoring
On holiday recently following 6 weeks of chest infection I was breathless and dizzy on climbing stairs or going uphill when walking. I bought this to diagnose my irregular heart rhythm ( I am a retired doctor) whilst I organised a medical review. I found it very helpful as the quality of the single lead V5 ECG is very good. I was able to present this to the doctor when I saw him. Whilst I wait for further investigation I am using the device every day in the gym on the treadmill. I find the ECG the most useful piece of information. The heart strain reading I am not so sure about because I think it may be misinterpreting this due to the fact I have 'ectopic' beats. It's still early days but I am impressed with this device and the quality of it's build and software. I'll add another review as time goes on.

It's a total game-changer for me
It's a total game-changer for me, especially with its "Mark an Event" feature. I've suffered from Afib and this ECG wearable changes everything for me. I can share my data directly with my cardiologists and has saved me many a visit!
The vibration alerts is my second favourite feature because it leaves me stress free. I don't need to worry about pushing my heart too hard because this device is there to warn me before I cross my limits. Great customer support and helpful team!

Game Changer for Heart Patients
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.
