Ranked in these QuestionsQuestion Ranking
Pro Good for the casual user
The Link is simple and easy to use, but doesn't come with the more hardcore options that an advanced user would look for.
Pro Customizable bands
The hardware is removable, so you can swap the bands for whichever color you prefer.
Pro Tough and comfortable
It's made from a single, strong plastic band that won't snap or break. The strap feels soft and stretches slightly, and includes clasp holes along the length of the band so you can set it exactly how tightly or loosely you want.
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.
Pro Small and light
It has a focus on being small and comfortable, and definitely hits that mark. It measures about 20mm across, and weighs in at around 30 grams.
Con Decent battery life, but doesn't hold up to the competitors
On a full charge the Link should last you around 8-10 hours of usage. When taken into consideration that this is simply a HRM, that's not so bad, but it still doesn't hold a candle to some of its competitors.
Con Accuracy can leave something to be desired
Under lab conditions, the Link has been shown to be accurate within -27 BPM to +29 BPM. If you're looking for accuracy, you'd be better off with a chest strap HRM than the Link.
Con Doesn't read your heart rate so well underwater
The Link is designed for runners, so the accuracy while swimming leaves much to be desired. You'd be better off with a HRM designed specifically for the water.
Con Uses a proprietary charging dock, so you have limited charging options
Unfortunately, you can't use any old QI charger to charge the Link. It comes with its own charging dock, and that's all you can use.
