I only use it to measure my heart rate and compared to my Apple Watch 5 it seems pretty accurate. Works great with Zwift on an iPad and a 5 year old Garmin Edge 510. I only use it for cycling. So far, there are no problems with signal loss and accuracy. And I love that the Japanese language is printed on the packaging. I wonder if this product is mainly sold in Japan. This means that a certain quality or criteria have been reached in order to be able to sell there.
