Pro Easy to check heart rate mid run with a built in LED system
The Link comes with an LED that gives you a different color depending on where your heart rate is at. This makes checking your heart rate a lot easier as you don't have to stop and pull your phone out, or risk dropping it while you're running.
Pro Connects via Bluetooth and ANT+, so you have a wide variety of connection options
The Link can be paired with any app that supports a heart rate monitor and does so via either Bluetooth 4.0 or ANT+, whichever you prefer. It can feed information to either your phone, a GPS watch, or even your bike computer.
