Solar is a bust
on April 27, 2023
Posted by: Gyre
Pros:
- Seems to be more responsive than 830
- UI is easier to navigate than previous iterations
- Buttons + touchscreen is a welcome change.
Cons:
- Solar option makes the screen way too dim, doesn't add much charge at all. This is essentially a niche option for people who value charge time above all else and don't want to use any kind of external power.
- No organic support for Tyrewiz

Great upgrade
on April 27, 2023
Posted by: Gabe1971
Bought the 840 Edge Solar on the day of the release, so far a good experience, a decent upgrade from the previous 830 owned for about 4 years. The graphics are better, and the buttons are a very much needed plus, as I had some issues in the past with water dropping on the 830’s touchscreen and getting completely crazy from there.

Love the Touch Screen AND Buttons option
on April 28, 2023
Posted by: Clintg
This replaces my 830. I find myself using the buttons on this device more than I thought I would. I love the option of both buttons and touch screen, as I use both in different applications. Setup on this device was very easy, and I like how it paired the sensors that were paired to my 830. The new UI is intuitive with a lot of information. The solar feature doesn't really change the device (maybe like 1/2% per hour when off), but it does help extend the battery. This is a great size for both mountain bikes and road/gravel bikes.

Nice evolution
on May 5, 2023
Posted by: JPro
I bought this a month ago, the features are what I wanted and was expecting. I need some longer mounts to more easily reach the lap button, and there is an occasional glitch with it telling me a segment is about to start, and then the "GO" box staying there the entire time, but that is most likely a software issue that will be rectified in an update. Nothing I would be upset with in a new product launch. I have had this since the day after it was available.

OK, but lots of room for improvements
on May 10, 2023
Posted by: LanceAndre
Negatives: horrible GUI; useless default screens; Power screen gets interrupted by hill screen; Solar screen is not worth the diminished visibility; huge bezel with nothing printed (how about labeling the button functions - I'm all the time hitting the lap button by mistake).
Positives; lots of great metrics and feedback, good run time.

Not enough memory
on May 14, 2023
Posted by: Ale15
Bought a 1040 Solar and a 840 Solar. The 1040 is great with enough memory and more. The 840 right from the get go prompted me to delete maps for regular software upgrade! That’s disappointing!
