Button placement awkward
on May 5, 2026
Posted by: DarBen
I bought to replace a Garmin 1000 which finally stopped working after about 8 - 10 years... loved that product! The Garmin 840 Solar seems ok thus far... however I think the button placement could be better. I feel like there is not a good way to turn it on without your fingers touching other buttons or not getting a good grasp of the device.

Had it for a month. Love knowing there is a car behind me. Works great with the radar and front light and the cadence sensor. No complaints whatsoever

I have been using Edge Cycling computers for many years. They are an excellent tool in every manner of training and ease of use. This one just took more time to set up and get used to.

Unacceptable failure
on April 20, 2026
Posted by: Whoops
I’ve had this device two years and it has worked adequately. Then it died on the middle of a cross-country bike tour. For a device that is supposed to be rated to help navigate in the backcountry, for it to die under such non-extreme circumstances is totally unacceptable. It had trouble managing a route navigation and heart rate data, don’t trust it with your life.

Charge it and forget it for some time

I got the Edge 840 Solar to replace my old 520. The 840 is touch screen which is easier to manipulate. Being solar, allows you to enjoy longer rides and much fewer battery charges.

Pain in the rear.
on January 19, 2026
Posted by: Dirk Diggler
I race road and track. I need a computer that basically captures power, lap power ave, cadence, HR, time, and speed. Everything else not a must need. The touch screen is a huge pain on my tt bike because the position of the computer slightly rubs my arm. Thus results in the screen changing. Also if screen is smudged if you try to wipe it off during ride screen changes. If you like a Lot of functions that are not relevant this is the computer for you.
