Review on Enhance Your Running Performance with Garmin's 010-12520-00 Running Dynamics Pod by John Koch

I'm very happy with Garmin products, have had five or six Forerunner watches since the venerable old Garmin 305. I bought a Garmin Run a Dynamics Pod and excited to try it across the world at a marathon in Hangzhou, China. It's sad to say that I've found that the brand new Running Dynamics module I bought from Revain to work with my brand new Garmin Forerunner 935 doesn't seem to work: I've tried everything in the guide including the Shaking the Module Wake him up. and pairing the module manually via the menu. Apparently the device is not sending a signal or pairing information to my watch. Too bad - I ran the Hangzhou marathon, but didn't get any useful data on running dynamics. It would be helpful for users and buyers of this device if there was some kind of status indicator to show that the device is on and working. . As designed now, it is a mysterious black color. uh, yellow box. I will update this review with my review of the device and its details when Garmin ships me a working replacement.
