Reviews
Really impressed with the X2 device. The heart rate appears very accurate and the ECG downloads are very detailed and useful. I use it to see my heart rate on the Peloton bike and the Frontier App to record the ECG to view afterwards. I had a technical question about how to see the ECG in more detail and the customer support team walked me though how to use the web portal as well. Thanks
