Used Fenix 5 - is this normal usage? : r/GarminFenix
Update: I had posted before about the cracking Heart Rate Monitor on my 5x. I contact Garmin and they replaced the watch. It was great customer. : r/ GarminFenix
The HR sensor glass of my FR645 is cracked and I don't understand why. I literally only take off the watch to charge it... Did this happen to anyone else? : r/Garmin
