I've been using Garmin products for a long time. My previous bike computer was an old Edge 130 and after I purchased an Instinct watch I moved over to it for most of my training. Recently I got more serious about my training and needed a better computer to follow the workouts I was creating and doing, so I moved up to the 840. It's more bells and whistles than I really need and the settings have some features that default to 'On' that I'd rather configure for myself. E.g., "Why does it keep beeping at me every time I reach the east end of the velodrome? Oh, it thinks I'm about to cross I-75!" I've created a 'Velodrome' activity specifically for my track sessions. And when I'm riding on the road I don't need it to switch the display to a map and show me the grade that's approaching. I'm sure that as I use it more, and take the time to configure it to my particular preferences, I'll be happier with it. But I'm sure that once I do, I'll only be using about a third of all the features it provides.
Long time road rider. I have worn out the battery on 3 varia units, much quicker than the head unit battery. The battery charge lasts through a couple of long rides, same as Garmin. I am hoping, but don't know, if it will do better than the varia at holding that charge 2 years from now. My hope is based on a newer design and electronics. The mount is sturdy, and easier to secure to the seat post. Some of the features are controlled through a separate app, although you won't need to use the app after initial set up. Radar function works as well as the Garmin, and there are more flash patterns, the light turns off if there are no cars detected, and it has a brake light function.
I had a night rider light before and liked it. Unfortunatly I misplaced or lost it after I had it for 6-8 years.
So I love my new nightrider light even more because it is smaller, and more powerfull. The different brightness modes are awesome and easy to change.
Also I like the nightrider light because it is being manufactured in San Diego were I live and ride. I went to their shop once and had my older light rebuilt under warrenty.
this replaces a wahoo elmnt bolt that worked well for many years, but finally died.
this device looks and feels of good quality. it is rather large compared to bolt, but this is due to the solar battery-related. fine with me. it is not heavy.
screen and maps are legible and easy to access on bike
Coros set up app was easy and synching with strava was straightforward
battery is amazing. i received it fully charged and after 12 hours of use still has >50% original charge. i have never needed to charge it.
