“Battery life is excellent, I've got mine to about 10hrs now with full brightness of the screen - that's enough for me. The vvariety of screens available is excellent and I've taken a few weeks to tweak the screens how I want - GPLama's YT videos were most helpful there. I'm reducing by one star because I wish I bought the 1040 or 1050 (although I would never have paid that price!) because some more screen real-estate would be helpful with my fading eyesight - that's a me thing so possibly unfair on the 840. I reckon its the sweet spot of price and capabilities, and the integrration with Garmin Connect is outstanding. Cheers Sean”
