I've had all sorts of problems with my Garmin computers communicating with my iPhones over the years, but one thing that has never given me problems is my Garmin heart rate sensor. It has worked flawlessly for me.
Well now I can add another to that category. The Vector 3s synced with my Edge 1030 first time and every time. It was easy to install, and so far, no problems.
The one thing I wish Garmin would do is provide online videos on how to use their product show to get the most out of them, how to make use of less well-known features. Instead, the videos on their website are promotional only, and no use to anyone who already has their product. Instead, it is left to third parties on YouTube not only do you have to search for these things, but with new products they don't even exist.
I changed from P1 powertap to Garmin and only have good experince with the pedals
Changing batteries is the worst! Sometimes the unit works and other times it doesn't.
