Have been using for 2 months now. Using for Road and Mountain cycling. I highly recommend this unit. The elevation and power meter options are Awesome as well as crash detection. The Jump and grit and flow are great. I have a Garmin Varia and it work with this flawlessly. Switchs between bikes in seconds. I couldn't be happier with this Garmin product.
Garmin is still the standard in bike computers. Plethora of mounting options. Some of the mountain bike features are cool, but I don't find myself looking at them often. The mapping/trailforks integration is nice, but leaves alot to be desired. I still find myself looking at trailforks via phone for navigation.
So far this unit has been working as advertised. Only one hiccup so far of the Edge 530 randomly restarting during one ride, but it did pick up that ride and continue as soon as the reboot was complete.
