Well the watch and the cadence and speed sensors seem to be doing fine. However the premium HRM strap is a POS. It would not pair to the watch so I read on the forums that plenty of people were having to reverse the battery polarity and it would then pair. So I started trying that and 2 of the 4 small jewelers screws stripped like melted butter. And I have worked in the electrical and instrument tech rhelm for a good amount of time and I was using a prober jewelers screwdriver. I ended up having to drill out the screws and of course I slightly damaged the plastic when I finally made it through. You swapped the battery polarity and still nothing.

Not sure what I want to do there. I might just return it to amazaon and try a better ant+ hrm and the other option is to try getting a replacement from garmin. Any suggestions?
