Garmin Bike Computer

[Bradley Brooks]

I purchased the Wahoo Elemnt Roam v3 last year and it had some  initial issues but nothing since the last few weeks. This bike computer has not been syncing activity history, and the computer battery is not holding a charge. Seems to me it is time to move on to Garmin.

I have been looking at the Garmin Edge 840 & 1040 Solar as well as the Edge 850 & 550. I am most concerned will battery life as on long brevets I do not want to be concerned about charging my bike computer. Does anyone have any recommendations or thoughts on which model is better for randonneuring?
