Yes, we have been testing the Mio Link, a heart rate strap for the wrist.
An accurate heart rate monitor can help you train in the right heart rate zones, recover faster after each workout, and stay on track toward reaching your fitness and performance goals.
While testing the Mio Link I found the strap comfortable, & an accurate alternative to heart rate monitor chest strap, the strap transmits heart rate to smartphones, GPS watches & bike computers. I am the least tech savy person around, was able to sync the Mio Link with Polar and Garmin watches with ease.
I further tested the Mio Link with my smart phone and used the free Mio PAI app which translated the heart rate data into a meaningful activity metric. I found the proces easy and simple to download and sync with the Mio Link.
