I've been using it for a few weeks now and I haven't found any faults yet. The watch does everything it is supposed to do.
I bought the Garmin Forerunner 965 and I'm totally happy with it! Great AMOLED screen, intuitive interface and accurate activity measurements. The battery lasts a long time, even with intensive use of the GPS. An ideal watch for running and other sports. I'd definitely recommend it!
The 965 helps you properly monitor your health, including sleep, rest and even naps. It offers handy support for training and workouts. Recovery time was already available with previous Forerunner models, but now the device also tells you if you are ready for your next workout.
