"I ordered for a friend, he happy with it."
"I've used most of the cyclecomputers on the market at one time or another. The Garmin Edge 830 was my favorite for a long time, so I've been eagerly anticipating the arrival of the 840. I went with the 840 Solar thinking I'd need to charge less frequently and as the battery aged the computer would remain very usable. What I didn't anticipate was that the screen on the 840 Solar is dramatically dimmer and harder to read than my old 830. I'm really shocked how bad it is, and while I've seen reviews that casually mentioned that the screen is dimmer, they didn't convey the seriousness of the problem. On my 830, I never took my computer out of "auto-brightness" mode and never felt a need to tinker with the screen brightness. It was perfectly fine in my opinion. On the 840 Solar, with auto-brightness on it's difficult to read indoors or outdoors in late afternoon conditions. Don't get me wrong: It's not like it's illegible, but it takes more focus and attention to read than the casual glance that works with every other popular computer in the marketplace. I have to set it in manual mode and crank the brightness just below the battery consumption warning level to have a reasonable result. This is all without wearing polarized glasses by the way: I can only imagine how bad the experience would be with them. If Garmin released a software patch that made the auto-brightness brighter on the solar models that would help a bit. It would also consume more battery power, and you have to wonder how much of the extra power you're getting from the solar cells is going right through to the backlight. The bottom line is that the "Solar" option should be treated as a niche product and never a no-brainer. If you need every drop of battery endurance, refuse to charge from an auxiliary battery, ride in extremely bright conditions, and you're pretty indifferent about screen brightness, then this is probably a good choice, but I definitely wouldn't recommend it for the average rider. Outside of the solar/display brightness issues, it seems to be a decent (if uninspiring) upgrade. I haven't done empirical testing, but the computer seems to run faster, so for example, the latency between shifting gears on an electronic system and seeing the gear display update feels improved. The UI is not fantastic, but seems a little nicer to navigate , with a similar feel to the inReach Mini 2. Having both touchscreen and side buttons together is a welcome change. USB-C is long overdue. It is disappointing to see that Garmin hasn't added any new data field layouts, and the lack of organic Tyrewiz support is lagging the competition. If you're looking to get a first serious cyclecomputer, the non-solar 840 is probably going to be a solid choice, but if you have a 530/830, this is largely going to be a matter of incremental improvements."
