I've enjoyed having a Fenix watch. I used it hiking and skiing, and to know what time it is, it's nice having just one thing to charge. The down sides are that power based workouts are harder especially short intervals. And the map is useable but a step down from a 1030.
I would definitely want to avoid a factory reset too! I don't know how this part works, but if you have to go down that road, I know they made it so when you upgrade your data screens move over to the new unit. Maybe somebody can clarify if you can use that to bring them back after a reset so you don't have to do all that again?
