5 stars and well deserved. After a few years my FF HRM was becoming problematic. It took a beating so I was not surprised. Just before a major cycling event it stopped recording my ECG. I have some heart challenges so I monitor my ECG carefully. This was a big cycling event in three days. I contacted customer support and they FEDXed a new device to the hotel I was staying at in approximately 24 hours from when I first called them. The customer service rep. Sahid followed up repeatedly with me and made sure the process was flawless! Totally awesome customer service. I got the new device with plenty of time before my cycling event.

This is by far the best heart rate monitor on the market! I'm currently in cardiac rehabilitation after experiencing a heart issue while training for a mountain trail race. My cardiologist recommended Fourth Frontier because his cardiology department uses their monitors for an innovative Sports Cardiology Rehabilitation Programme designed to safely return performance athletes to competition. In my case, the monitor sends data directly to my cardiologist and physiotherapist for analysis, providing them with real-time insights into my recovery progress. This level of professional-grade monitoring gives me confidence that I'm training within safe parameters while working toward my goal of returning to competitive trail running.

Client services is just great. I had a technical issue with my device and they reacted very fast and were able to help me. Amazing experience!

Really great technology! Ive used bio strap and my Garmin watch and I've seen other comparable bio metric devices in person but nothing compares to the frontier X!

Client services is amazing. I had a technical issue with my device, I don't live in any of the countries serviced but they managed to send whatever I needed to me. Great experience!

The X plus provides truly a medical grade ECG. I am a physician with both atrial and ventricular arrhythmias. The X plus provides a comfortable and accurate way to monitor 24 hour ECGs both during activity and sleep. It is both more convenient and gives a better read than electrode based systems that I have used, which often fall off or cause skin irritation.

Although the courier (Evri) really severely let down this retailer the customer service was second to none (Poonam). Thank you. 🙏🙏

I've been using the Frontier X ECG device and want to highlight how impressed I am—not just with the technology, but especially with the support team. Their responsiveness and willingness to help has been exceptional. Any time I had questions or needed assistance, they were quick to respond and incredibly helpful. It’s rare to find a company that stands behind their product with such dedicated support. Highly recommend! One tip for new users: avoid wearing exercise clothing that retains static electricity, as it can interfere with ECG signal quality. Stick to natural fibers when possible for the best results. Highly recommend!
