With a responsive touch screen, we can easily swipe and tap to any screen as we ride to access personalized coaching, workouts, stamina insights, and more.

Overly complicated with unhelpful manual
There is no doubt that the edge 840 is feature packed but it is unnecessarily complicated to set up and too prescriptive in terms of defaulting to workouts and performance rather than having those as a choice. Yes there are useful features but basic data should be there out of the box with anything else a matter of choice.

Nice computer
Nice computer with a lot of features (more than I have delved in to). It synchs easily with my iPhone via the Garmin app. The battery easily lasted for a 10 hours day ride at Leadville.

Informative
A lot of Information to gather after a ride. Yes, it's more than I would ever really need, but it is nice to see all the metrics.

Solid Data Tracking
Been using this for a couple of years now, easy to navigate the menu, Works GREAT even in low temps (single digits). Battery life is fantastic in all temps. Some adjustments should be made to get this a 5 star. No way to auto power off (only sleep) so if you leave the unit to download your activity and forget then the battery goes dead. Older units had this feature. 2nd fault - once you enter an activity you have to lock the screen to keep sweat or rain from changing your layout. This should be automatic, seems the opposite. Last thing they should build in Bikes and Gear for you to choose in an activity rather than needing to go to the app afterwards to choose this. All in All I highly recommend Garmin Edge GPS units! these items are small inconveniences.

Great bike computer but takes a long time to figure out how to set up the screens. Definitely better battery life than some other computers out there. I like the maps.

Fantastic for Anyone
It is the perfect bike computer for the casual or experience. The screen is the perfect size to be able to see it, but not too large to where it looks like a phone on the front of the bike, but not too small where you cannot read the data screen as well. It pairs very easily with any external devices, such as lights or radars great recommendation would buy again.

Got this for long rides so I don't have to rely on the battery life of a watch or phone. Great battery life. Screen is plenty big for me. Easy to load routes. Touch screen allows you to zoom in/out easily while riding. The colors on any of the map settings are hard to see though. It's difficult to distinguish route from background. Also you can't turn the screen off, which can be distracting.
