I just got the F5 Thursday and have been playing with over the weekend. I did three runs at 15 miles, 5 miles and 6 miles.
I wore all hours of the day.
The battery life seems to be find.
I noticed the Bluetooth strength is very weak compared to my forerunner 230.
I took a look a 2 runs with the same route on different days, one with 230 and F5 and the F5 had a lot of sharp cuts when turning corners while with the 230 are more rounded.
I notice the running pace to be different the 2 devices. F5 seemed to jump or slow to change, some times I feel like I am going slower but watch say differently. With the 230 "felt" more accurate or what I was use to seeing as I have run 3000 miles with the 230.
RHM Tri with the F5 seem to be lower then the HRM with the 230 but I cant say that its off with the F5.
I love the look of the F5 compared to the plastic 230.
I have 30 days for return so I want to try it out a week or so before deciding to return or not.
Is the GPS and BT on the F5x have the same issues as the Fenix 5?
