The device measures the heart rate about twice as high as it actually is. I went to Wahoo's support site and tried various suggestions to get the device to measure correctly. None worked. I contacted Wahoo Support via email. In the email, I summarized everything I had done to get the device working and provided a photo of the heart rate measured by the blood pressure monitor at the same time my heart rate was being measured. according to TICR. The photo documented a factor of two discrepancies. Apparently Wahoo Support didn't read my email because they just sent me a link to a website I had already accessed to try and get the device working. One suggestion on the website that I didn't try was to replace the battery on a new device. I even tried it, but it didn't help. My experience is that TICKR doesn't measure my heart rate accurately and Wahoo's email support is useless.
