Review on Jaybird S/M - Black: Stylish and High-Quality Wireless Earbuds (Discontinued by Manufacturer) by Walter Hodzic

I REALLY wanted to like this device. They create the right product, but it just doesn't work. I run local races and need an activity tracker that includes heart rate to get an idea of how my recovery is going and if I'm overtraining. Unfortunately. , I couldn't get the display to stay responsive, the iPhone app often couldn't find the device, and the Go Zone only worked one morning out of five. I was willing to forgive a lot and wait for an update. This device looks like a pre-beta and I'm just not sure if this company can deliver on the promise. In the end, I think it will be easier for me to assess my recovery with an all-purpose tracker that actually gives me the data I need. Next I will try the Fitbit Charge HR. My Reign is on the way back in a box (and I'm tinkering around).
