Long-time Garmin FR user... started with a FR305, moved on to FR230, then 935, then 745, and now 265. 4 days in, and I'm LOVING this watch so far. My 52-yr old eyes appreciate the AMOLED screen for daily use (including outdoors, sunny days are no problem). The accuracy of the wrist-based HR during runs is spot on to my HRM Pro, and the elevation tracking is also spot-on. Fingers crossed a software bug doesn't ruin my experience, but I have zero complaints on the 265 at this point, which is more than I can say for any previous FR I've owned.
