This thing is amazing!
Style: Edge 840
Seriously, I'll never use more than 25% of what this thing does. But I'll never ride without it again. I have a profile for road and another for mountain. The customizable screen lets me see exactly what I want and need and nothing more or less. It's a bit fidgety to learn, you will need to spend some time, but it's so worth figuring it out. Sometimes I just go ride. I point at a landmark feature and just go. It has saved me from getting lost in the burbs and the wilderness many times. The return home feature is outstanding. Other times I look at google earth and plan a route that I've never been on before. Using Garmin connect on my PC I've been able to plot trails to exacting accuracy. Then upload them to the Garmin. I always end up where I think I will. Battery lasts for many rides, for me. (My rides are usually less than 25 miles.) My only complaint is that it's hard to talk some of my friends into buying one because of the price. In my opinion the price is justified. I wish my friends would take the plunge because another feature this device has is pairing with friends. They will become blips on your map. You'll never lose a rider again! Brilliant piece of kit. I've never used a cycling computer before but it's better than any app I've tried on my phone. even the one that came with my ebike. The Garmin automatically connected to my bike and shows me all the pertinent metrics. ... show more

Best Garmin head unit yet
Style: Edge 840
I have been a Garmin user for many years. I love all their products. I have watched as their products have become more reliable and user-friendly. The Edge 840 is the latest, and in my opinion, the best of their head units. Everything works and works well. The wireless sensors, the rear radar unit, the front headlight, the HR monitor—they all work great together. Syncing up all the various components and sensors is seamless and works right, every time. As a bonus I can sync up my Dexcom G7 CGM and get instant glucose readings during my bike rides—no more fear of bonking during a long ride. The touch screen works great, not even raindrops, or perspiration, affects the display. The 840, unlike the 830, also has buttons which work effectively and quickly. The new GPS chip is far more accurate than in the past. The Climb Pro feature is awesome. The 840 has far more features that I could ever hope to use, but the features that I do use work exceedingly well. If you are deciding between the 840 and the 540, I would recommend the 840. ... show more

Garmin Edge 840 feedback

The Garmin Edge 840 is a powerful and reliable cycling computer that delivers an excellent overall experience, especially for riders who value navigation accuracy, battery efficiency, and advanced training insights. The combination of a responsive touchscreen with physical buttons makes it easy to use in any weather, and the interface is fast, clear, and customizable. Value for money is good. ... show more

Updated with new User Interface
Style: Edge 840
The operating system has been updated with the new style also on Fenix 8 and other models I'm sure. Both touch screen and a full set of buttons makes operation easier. Both the GPS and Heart Rate are noticeably more accurate. Even though the screen is the same size and same pixel count, it is more vibrant and easier to read. Upgrading from Edge 530/830 was a breeze since all the customized screens for different activities easily ported over with a single command. Overall a nice upgrade with zero complaints. ... show more

A fine product!
Style: Edge 840
Review Image by Richard L. Grendell
I have had the opportunity to put a couple hundred miles on my 840. It has been a pleasant upgrade from my 830 (which had about 25,000 miles on it before the faceplate started to separate from the device). While the 840 seems slightly dimmer than the 830, I have adapted to this attenuation and hardly notice it now. The screen of the 840 is sufficiently large and the display is bold and quite prominent. Overall, I am very satisfied with my purchase and am enjoying the device immensely on my gravel bike! ... show more

Over priced but not bad
Style: Edge 840
A bit hard to navigate through it. Setting up a route is not user friendly, i gave up on it. Would be nice to be able to plan the route i want without the difficulties, i was excited to set up my routes on it but that quickly faded. Definitely a bit over priced all around. Size is okay, good and compact, seem durable enough. Connectivity is good so far. ... show more

Fast cycling computer with great graphics.
Style: Edge 840
Fantastic cycling computer. Bought this to replace my aged Garmin 520. The speed of the computer (not me) is much improved, as are the graphics and ease of use. Setup was also quite simple and I was able to use my existing sensors.
