The response to my inquiry was prompt and thorough

Nach mehreren Episoden an Vorhofflimmern habe ich mir den Frontier X2 zugelegt. Ich freue mich über die Beruhigung mögliche Episoden während Trainingseinheiten oder im Schlaf auch diagnostisch erfassen zu können und den behandelnden Ärzten ein 1-Kanal EKG zur Verfügung stellen zu können. Den Support habe ich jetzt zweimal in Anspruch genommen - beide Male schnelle und lösungorientierte Unterstützung bekommen. Klare Empfehlung.

Very friendly, kind and customer focused support. My technical issue was picked up and solved very quickly.

Excellent product, I had Afib and it helped me to understand which activities brought it on, sleeping and exercising in my case. This also helped me make the decision between medication and ablation. Customer service is also top notch. Quick response times very knowledgeable.

I’ve been using the FrontierX HR monitor for nearly 6 months. Firstly to track a mild exercise induced atrial arrhythmia which I then shared with the cardiologist who was then able to diagnose together with stress ECG. Secondly to better define my training zones via breathing rate / metabolic analysis for VT1 and VT2 for triathlon. I used the online fourth frontier analysis tool together with my own ramp tests and FTP tests to nail my “easy”, “moderate” and “hard” intensity zones with power, heart rate and breathing. Very powerful- to the extent that pro-cycling teams are doing this now. Easy is now easy and hard is hard. No straying into grey moderate workouts. This helps to recover faster and maintain training load. I’ve had a few issues - mainly software and reboots - but customer service is really fast and very high quality in terms of troubleshooting and fixes. Given the accuracy and precision of the monitor I’m amazed at how small, durable (I’m a heavy sweater) and robust it is. Overall very good!

Amazing product. With a ECG during workouts gives a lot of insights to the heart.

I was not seeing data i expected. The tech team quickly identified the issue and provided a recommendation.

I've been using my X2 for several years, and have encountered a few challenges (mostly software related). Every time, the service team is on it. They fully research and respond to every request - that's incredible! It's more than an HRM, and it allows me to continue pushing my physical limits while keeping an eye on my artificial heart valve. Thank you.
