Lots of improvements, some challenges
- Familiarity:
- I've used it several times
- Size Bought:
- N/A
Upgraded over the Edge 530 (damaged screen). Went with the 840 with touch screen because I'd heard of the UI navigational challenges AND Garmin equipped the 840 with the same buttons as the 540 so you can use it without the touch screen as if it's a 540. The UI Is different and the defaults definitely need to be changed if you're coming from a prior Garmin. So far I mostly use the buttons but the touch screen has been helpful in shortcutting menu navigation. Screen and battery definitely improved. Haven't been to the spots where I hope the GPS improvements will be noticeable. Extra storage space on the device helpful but need to reduce maps to take advantage. Overall build seems more solid too. Hopefully holds up better to MTB wear and tear. If you're a Mac user be warned there's challenges getting Garmin Express to work, so far transitioning data from my old Edge was next to impossible so I bailed and borrowed a Windows computer to transfer the files. All good now but still no Mac access (yes, all elements updated to latest versions).

Complicated
- Familiarity:
- I've used it several times
I chose and bought the Garmin Edge 840 Edge mainly because of the touch screen option and the hill focus. I'm hoping that one day soon, maybe by next summer, I'll get to completely enjoy these and everything else it has to offer. It's so complicated. Not only are there 7 buttons but many have dual functions. The on-line manual is of little help with no "quick start" section for new users. Like I said, I'll keep studying and hopefully by next summer.

To much going on
Sorry I do not like it, my wife purchased this unit for me at your unbound gravel expo booth. I would like to send it back to you. I understand it's used now but I have taken it off my bike and going back to the other brand. To many things going on, things I don't care about and to many buttons to try and navigate through while riding my bike. Can we get it sent back?

Great product that has become obsolete.
I am sorry, but bike computers are obsolete. Just get a decent phone case, download the Strava app or any other cycling/activity app and avoid yet another $400 gadget that we dont need.

Edge 840
Replaced my 8 year old Garmin 520. Im glad I went for the touch screen option. This is a quality product in typical Garmin fashion. I only wish Garmin would improve the intuitiveness of their products

Some improvements, but a couple of annoyances
I bought the E-840 because, after 5+ years, battery time on my beloved E-830 was weakening. If upgrading from the E-830, there IS a learning curve! It seems to remember the censors to which it is paired a bit better than on the 830 (especially the cadence as I use this on two different bikes. However, some NetIQ apps are gone, and the NetIQ "store" is a mess right now. Even if searching for an Edge applet, you will be presented with hundreds of watch faces! The new chip in the 840 is much faster than for the 830, which I appreciate on climbs. The display is also a bit larger - great for those of us in our 70s! Also, navigation prompts appear to come more quickly than before. The annoyances - it beeps for too many reasons, many of which I have yet to determine. After a ride is completed, it takes a LONG time to sync with my phone, even though the display claims it has. Too often when looking at Connect, I have to go back to my Edge and power it on and wait for the upload to complete. What it will sync to is my RideWithGPS library. It copies each ride (aborted or not!) to my RW-GPS library, cluttering it up. (I could probably find a way t stop this, but...) After I complete a ride, things get a bit confusing. I hit the stop button, but rather than showing the default fields for my profile, I get a long list of options, etc. Up in the corner, I see "Save" buttons, which recur as I scroll through the windows. Thing is, I'm never sure if I'm shutting it down in a way that does not destroy my ride data. (Oh yeah - sometmes when it syncs I find the ride was entered ot a time 12 hours previous. It's getting better now... CONCLUSION - if this is your first Edge, or if you are upgrading from a 500 or 150, it is absolutely FABULOUS! If you're upgrading from an 800, you're facing a learning curve and some work. Still, I'm glad I bought the 840!

On the fence
Hopefully I will update. I am pretty sure that eventually I will love it. The learning curve is real. I have spent quite a bit of time with youtube and manuals, but I am still struggling

840
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 sites. (Regardless, I will be making a trans-America bike ride May 2025 + would not do it without such Garmin technology)

Sweet when it works...
- Familiarity:
- I've used it several times
I have had nothing but troubles with this computer. The touch screen is nothing short of finnicky.... This is like the original touch screen cell phones... Mediocre at best. Tons of what appears to be software issues. The few times it does work its pretty sweet. I would NOT purchase again.

It has potential
I bought this a few weeks ago and I can’t get it to sync with the heart rate monitor and the cadence only shows sporadically. I love the touch screen, much easier than my 830.
