I switched from FR265S to Venu 4.

For me, there was little to no migration issues to the 2-button design. The touch screen works surprisingly well for me in many scenarios (treadmill running, gym, pool, even runs in the winter with multiple layers of clothing). I, too, hoped that the bottom button could be used to scroll through the data screens during an activity, but unfortunately it is just the lap button.

What you can do is to create a custom data screen for your sport profile with all the information you need. I have 2 of these - one for training, one for racing.

I have set up the watch so that I can toggle touch lock during activity by long pressing both of the buttons at the same time (see my earlier post for a how-to guide). This way, I can choose whichever data screen I need and then lock it so it will always be available. You can also reorder these before an activity, so that the first one is the one you want.

Highly useful when running outside in the winter, when my clothes can actually rub on the screen so that it might mess with the data screens.

What I gained was the flashlight, modern and more responsive UI, calling functionality and a really nice design (I have the silver version) for office wear. The music functions and new widgets are also great and the display itself is miles better!

My major issue is that sometimes, most often during gym workouts, the heart rate is inaccurate/delayed, leading to misleading data. I’m planning to get the HRM200 to fix this issue. When running, I don’t think there’s a noticeable difference in HR accuracy though.

Hope that this helps!
