Upgraded from the Garmin 810 and I really leak the small unit. It fits much better onto my stem which I like better than the out front mounts. Touch screen is easy to use and once you've had Garmin units for a number of years, their functionality is simple to learn and use. Great product and a good price on Bike Tires Direct.
The elevation function using the satellites seems to have a lag in measuring your data compared to the Garmin 810. My wife's 520 usually has 600 additional feet of climbing on an average 3000 ft. day.
Moving up from my Garmin 500 to the Garmin 820 is night and day, I only have more pros than cons since I only had it only 2 months in use, but its definitely technology in the right direction.
Traded up, finally, after years with the 500. Works well but with two minor quibbles. First, the screen is more difficult to see in bright light. And secondly, when wiping sweat droplets off the screen, I sometimes inadvertently change pages, which can then be difficult to swipe, especially on the fly. That alone makes me almost prefer buttons instead. A little pricey compared to competitors, but okay if you catch a sale.
If you're as tied into Garmin for your training needs like I am, then this is a great addition. The data and its integration with Garmin Connect and other sites is great. The only downside is the touchscreen is not that great. The 800 was better but the 800 doesn't integrate with Varia Vision
I had a 510 that worked fine but I wanted to upgrade. The upgrades were the color touch screen, improved maps, and a few minor software things. The display is good, but essentially the same size as what I had. IMHO the 1000 is too big and the 510 is too small. The 800 seemed to be Goldilocks, but for some reason Garmin didn't stick with it.
I purchased the 820 to replace my 800 with map card. It is a little smaller and I like the new features like how it links to my iPhone. It came with an out front mount which was a nice touch. I like lots of data as I helps me focus on something other than how tired I am.
I previously owned a Garmin Edge 1000. I use the computer for training rides and racing - occasionally venturing out on long exploring rides. The map on the 820, although smaller, works just as well as the 1000 ever did. Sharp resolution. And the control buttons on the 820 are much more crisp and positive. I also prefer the smaller size.
Returned the Edge 520 go the Edge 820, both worked fine, however I wanted the touchscreen. This was an upgrade from the Edge 500.
Saving your data when paired to your cell phone is fast, getting you kudos from friends on Strava.
Im still figuring out all of the features it did cause an alert to my emergency contact when I stopped for an adjustment.
Love my Garmin.
Great product features. Good size, combines touchscreen functionality of garmin 1000 with the size of the 520. Rides upload immediately to StravaGarmin Connect via your phone or WiFi, you can see incoming texts and calls. Touchscreen though was abit of a setback. Abit difficult to use especially when riding. Does not perform like the smartphone screens to which so many of us have become accustomed. But overall, Im very pleased with the product, still a recommended buy.
All computers seem overpriced since upgrades are needed more often than I would like. Watch for sales. Others have complained about the sensitivity of the touch screen but it seems just right to me including when using gloves. The stop and onoff buttons are located on the bottomside to prevent accidental touches. Garmin seems to continue to lead all others in the field.
I also have an old Edge 500 (bombproof!) and an Edge 1000. The new 820 has a longer battery life than the 1000. The navigation is of course not quite as visible, given the 820's smaller screen size, however, it still navigates well...even on dirt trails. They have improved the software, with the latest update allowing 3 different 'sensitivity' settings for the touch screen.
Great unit. Customizing data screens is easy and can be changed mid-ride. Havent had to use navagation, but tested it out on local route and was very easy to use. Touch screen works good and I added screen protector and still works good.
I use the item on the road and CX. I like the small form factor and the placement of the startstop and lap buttons. I previously had an Edge 510 so I was familiar with the touchscreen. The Edge 820 touchscreen is not as precise as I would like it but it's doable. The performance metrics are a nice feature. It pairs easy with all of my devices. So far it's been working well given the discounted price I paid.
I bought this to replace my 510 since I like the touch screen. It's faster starting up with more features and a larger screen. The color navigation is nice. The battery life is poor, less than my 510. I can get 2-3 rides out of a full charge. The altimeter failed at 6 weeks and Garmin had to send me a new one. I miss the bike profiles from my 510 but the 820 had no problem handling all the sensors from 5 different bikes. Overall it's a big step up from my 510 but I think battery life could be better.
This is my second Edge. I upgraded from the 800. To keep this succinct, connectivity is simply fantastic. Screen size has me squinting. The reason for the less than perfect rating is that the apps are not tested to work well. For example an excellent third party graphical training page crashes the connectivity with the Vector power meter. Yes, there are resets and work arounds, but. In summary, this device is more an Android than an iPhone.
After reading and watching video reviews for the recent months after the 820's launch date, it appeared that it had some significant shortcomings for those users. However, I purchased my unit in mid-2017 and have not had the problems noted in their reviews. My unit came with software version 8.0, which may have solved their dilemmas. I find that the screen responsiveness is satisfactory for me even though it requires a more definitive touch than a smartphone. I later purchased a Garmin remote to jockey the 820's data screens easily while riding. An added benefit with the remote is that it keeps the flat glass surface free of finger and glove smudges, which helps me see the ride information on the screens. I like the 820's size. It's on the small side for mapping, which I don't use much. Heck, I don't even like big smartphones - I got an iPhone SE instead of the bigger iPhone 7 so it fits more comfortably in my pocket. So, far the group ride track rider feature is not too useful to me since older Garmins don't have that feature. It's hard to convince other riders to participate in that for my benefit alone. It may be a while before others purchase newer units such as the 820 and the 1020 for that to happen. I do use live tracking on every ride so my wife can monitor my location. My typical rides are 40-60 miles and I am away for three hours, give or take. It was a great upgrade from the Edge 500, but may not be worth it for riders with more recent Garmin units.
There are just to many kinks on the Garmin Edge 820. My Garmin 500 wasis great. Solid! But the 820 is finicky at best. Won't turn off 12 the time. The battery life is very short. Connections come and go, especially to the Garmin Varia Rearview Radar that I bought at the same time.
The touch screen is a pain in the '$' as well. If you like looking down and swiping 100 times, then this is the computer for you. I've tried several different settings and they all seem to work just as problematic.
I've only used the routing capabilities twice now and for the most part it was good. At times it would tell me to turn only to tell me I was off course for not going straight! Besides that quirk, it got me to my destination even if I ran off course by accident (or on purpose due to road work).
