I had my doubts I would like the weight and size of the 5X but I was wrong. It's awesome. Feels just like my old trusty F3HR. TBH, my F5 I've been running with this week feels a bit small because I was so used to my F3. The F5 strap IMO is too narrow for its weight as well. F5X has the nice 26mm strap so it doesn't bounce much at all. Feels same as F5 but a bit heavier. First run was good today. Tracked nicely, followed its loaded route, and OHR did well too. Getting maps, saphire glass, and Wifi is a no brainer for me. I'll pick F5X all day long. I DO however think it is a bit big for any petite runner be they woman or man. I am 6 ft, 185, but still have thin wrists. Still felt fine for sure while running...I DO think for road racing and intervals I'll wear my vivoactive hr because it's so sleek and light. However I mostly stick to trails.
