Good Product, But Setup Is Exceptionally Confusing

The 840 replaced an 830. I notice the 840 startup is considerably longer than the 830, which is irritating. I also see the startup screen is not a profile, but some other stuff I won't use. The page only goes away when I start the ride. And, Garmin being Garmin, the instructions suck and I can't find how to change this. Setting up profiles is confusing, and when I start the ride I have to swipe to get the correct screen. The good news: it was on sale because it's discontinued.

One Ride And Immediately Went To Get A Refund

I went for one ride. I was furious. The Garmin UI is terrible and the navigation is cluttered and unreadable. The UI customisation that is available in settings makes practically no difference. When I finished my ride I immediately went back to the bike shop to get a refund.

Wonderful Computer

Excellent device. Has always delivered and works so well for all my different rides

Dodge Gradient Results

Have been using my 840 for many rides. Past few months the gradient display has stopped working. Uphills with negative gradients, downhills otherwise but not all the time. Cannot find a fix.

Everything I Need To Know And More

Loads of features - invest in the time to trim unwanted screens and set it up the way you want. How much you want to see and what you want to prioritize is fully customizable. Consistent reliability. Provides battery info on the stack of sensors I have between my HRM, cadence and speed sensors distributed within my stable of bikes. I really like the Livetrack feature for keeping my spouse informed on my location as well as the incident detection.

Overall Works Well

I have used a Garmin Fenix 7 as my bike computer the last few years, and decided to step up to the Edge. There was a good deal going on, so I pulled the trigger. Overall I like it, but having one issue with connection to my front lamp. Going to see if Garmin can assist by reaching out.

Sufficient For The Task

This item functions as expected. I am learning how to use it and take advantage of all the features. That may take a while. 🤔

Awkward Menu Layout And Altimeter Doesn’t Work

Overall, this is a good unit. I like the amount of features that it has in the battery life. But I don’t like, is the clumsy/awkward menu layout that takes time to find things. I’ve had this edge 840 for about a month now, and still have trouble navigating certain areas. Today try to do a benefit charity ride in the rain and the altimeter stopped working a few miles in. Not the end of the world as the navigation still worked. But this seems like an issue that should have been fixed in the last version and it’s kind of frustrating when you are trying track stats and plan efforts on climbs. Wish I had known about the altimeter issue before I purchased.

The Device Crashes

When using the map the device crashes, it shuts down and after a while it turns back on. It's very frustrating as this happens almost every time you try to look at the streets around you, making it impossibile to find your curse if you get lost because the device keeps shutting down

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.

It's a solid MTB cycling computer! It does everything I need it to reliably.

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.

Good size and perfect tech to track my mountain bike and gravel rides.
