Easy to see when riding my mountain bike. Long lasting battery and the touchscreen works great. Having buttons to use also is nice if you have thick gloves on. Does everything I need and more. The maps are good too.

Pros: Touchscreen Battery life Included mounts Easy to see screen Can personalize to your own liking

Cons: There are so many tools and features that it can seem overwhelming to setup and use, but you can set up the basics and learn other functions as you progress and incorporate them into your settings and optional screens later.

I took the Edge 840 out for a 44 mile ride this afternoon with almost 2,000 vertical feet of climb. I took my time, and after 4.5 hours on the ride, it was at 85% on the battery. I really liked the climb feature, showing me how long an upcoming climb would be, the elevation gain, the percent of the...

Really pleased with the 840 solar. I found the device recalculated any route changes quickly, so there was no hanging about and I was able to navigate quickly on my route after any detours. The solar recharge worked really well and I had plenty of power in the device for the whole day.

Have had it for about a month. It regularly doesn’t connect to watch, di2, powermeter if left in sleep mode after saving a ride. But that’s the default for the power button. It’s annoying to have to fully turn it off and on each time when I commute daily and the battery should last at least a week...

Great product i had some issues riding in wet conditions the touch screen would glitch a little bit but overall this is my favorite piece of equipment and i would recommend this to other riders

I have used the Garmin 840 for about 6 weeks so far, guiding and/or recording many different bike rides totaling 450 miles. It has performed very well. Downloading courses from RWGPS is a snap. Navigating is easy. It does all that I want and more. I highly recommend it.

I am new to Garmin GPS devices + must express my exhaustion of figuring out how to choose preference of functions….How to input trips from other navigational Apps.If Garmin chooses NOT to include an instructional flowchart of options, setup + use, at least include a hardcopy of a few YouTube info...

Decent unit, integrates well with other Garmin devices/ sensors I have, all relevant info available at your fingertips but I’ve had some issues getting ClimbPro / Courses / Profile data screens to display as desired and to disengage Segment views even when you don’t want them. Hence 4*

Very good product. However, Garmin needs to either have more detailed instructions available, more make their products more user friendly. Takes a bit of time to set up and understand but once you have mastered it through trial and error it works wonderfully and provides great insight into your...

I bought this as an upgrade from my 520 Plus. I've only used it for a few rides but I am very impressed so far. I had the 820 but didn't like it so much because of the lack of buttons. I like that this has both buttons and touch screen. (Most of my rides throughout the year require warm gloves.
