What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Edge 840 is the most frequently recommended all-rounder in this pool. dcrainmaker.com's in-depth review highlighted the addition of multi-band GNSS and the combination of touchscreen plus full button controls as the key upgrades over the prior generation, and outdoorgearlab.com called it a strong balance of weight and functionality among Garmin's premier units. cyclingweekly.com echoed the feature-depth and longevity arguments.
What reviewers liked
- High-trust experts (dcrainmaker, outdoorgearlab) converge on it as a top compact computer
- Multi-band GNSS plus touchscreen and full button controls covers wet/glove conditions
- Up to ~26 hours of real-world battery is widely confirmed in community threads
- Deep Garmin ecosystem: ClimbPro, structured training, radar, Connect IQ apps
- Strong Amazon signal (4.6 across 351 reviews) corroborates expert consensus
Where it falls short
- r/Garmin threads complain settings increasingly require the phone app
- At least one community report of a snapped charging-port tab raises durability questions
- Interface is feature-dense; some riders find Garmin less intuitive than Wahoo
- Touchscreen reliability degrades in heavy rain per reviewer notes
- Price has crept up versus older Edge 530/540 generations

Community sentiment on r/cycling and r/Garmin generally lines up: riders cite the brighter display, faster processor, ClimbPro, and 26-hour battery life as standout points, with the touchscreen called out as the main reason to pick the 840 over the button-only Edge 540. The disagreement worth surfacing: an r/Garmin 'review/rant' thread complains that key settings now require a Bluetooth connection to the phone app, and a separate post documents a snapped charging-port tab on a first ride — durability and Garmin's app-dependence are real, recurring gripes.
The net read across mainstream tech press and specialist forums is that the 840 is the safe pick for riders who want serious training and navigation features without paying flagship money — and unlike the newer 850, it isn't being dinged for shortened battery life.

The display is much clearer and, thanks to the faster processor, the GUI doesn't feel like a car navigation device from the 2000s. I also ...
Bought my very expensive edge 840 Broken on first ride. Snapped the tab connector. I would avoid them like the plage. Why? It is too expensive.
