“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”
“Buggy, inconsistent responsiveness, sketchy altimeter, lost one of my rides even after it had been saved. RAM seems insufficient for tasks such as re-routing, I’ve seen watermelons more agile. Can’t seem to find a way to show heart rate during Climb Pro - when it would be a good idea to monitor one’s heart rate.”
