Frontier X2 Delivers
I have had the Frontier X2 for a few weeks now and I can say it does an excellent job of tracking my heart rate, breathing rate, and heart strain. The continuous ECG has been a useful tool for assessing a heart beat issue that was going on during exercise. I have looked at the training data and advice that this tool provides and once I start serious training again I’m looking forward to using these features. I did have one issue with the phone app but that was quickly resolved by an email to the Fourth Frontier support desk. Excellent customer service! From what I have seen so far I strongly recommend this device.
