What reviewers say about the Garmin Edge 840
Two whitelisted testers reviewed the Garmin Edge 840: DC Rainmaker (GPS/battery/solar instrumented) and Cycling Weekly (two-month hands-on, qualitative). Both call it excellent. They praise GPS accuracy, battery life, ClimbPro and the touchscreen, but flag gradient responsiveness, bulky map storage and feature overload.

Where reviewers disagree Genuine split on mapping/gradients: DC Rainmaker's instrumented tests call raw GPS 'basically perfect' and rank the Edge 840 the cycling computer to beat, while Cycling Weekly names mapping its 'biggest grievance,' citing wrong climb gradients and preferring Wahoo. Both note gradient-display lag, so the real distinction is GPS-track accuracy (excellent per both) vs gradient/ClimbPro display accuracy (patchy).

Observed battery burn rate (multiband GPS, 1s recording, 2 sensors): ~25-40 hours · Elevation accuracy vs other bike computers on same ride: within +/- 3 meters · Solar battery gain, 4hr 21min sunny ride: 26 minutes · Gradient display lag on short/steep climbs: 5-10 seconds
The Edge 840 delivers on what people want: An Edge 1040 in a smaller package.
GPS accuracy is basically perfect here.
you’ll typically see about 5-10 seconds of lag on the Garmin units.
There's very little to fault with this model's first update in four years, and it remains a truly excellent choice for any committed rider
it is in the mapping where I have my biggest grievances with this head unit.
the climbing page would say I was climbing a gradient of six percent when it was in fact flat
