Outstanding piece of gear!

I was concerned about connecting all my sensors on my bike and body and this thing picked them up automatically, which made this an extremely easy addition to my racing kit. Also the display of the information is vibrant and easily readable when on the edge of performance. This is the pinnacle of bike computers.

Not user friendly

I’ve used my new Edge 840 for enough rides to get a feel for it and I’m still unable to. The map hasn’t worked well and the climb notification is nearly impossible to find, even when I’m in the midst of a climb. My buddy has a Karoo that seems much easier to manage.

Great overall features

I have used my Garmin 840 a number of times on rides. The features and connectivity to my watch, radar and other seniors are great. Added features to warn me of traffic, turns and climbs is fantastic. Great addition to my riding.

Easy to setup

Bought an Edge 840and have used it 10 times in the last couple of weeks. Found it very easy to set up and use. Would recommend it.

Great computer

I purchased this about a month ago and my favorite feature is that it is simple to use. It automatically integrates with the garmin radar and keeps track of battery life of everything. I have not used all of the options due to my own issues but expect to within the next month.

Climbpro was disappointing

I bought this 2 months ago as an upgrade to my Garmin Edge 510. I really like the combination of buttons and touch screens. I was excited to get to my first climb to try out the Climbpro but was quickly disappointed as I can not read the numbers on the screen: Avg gradient, length of the climb and total feet of climbing. Those 3 critical data points are the smallest on the screen. My suggestion would be to get rid of the map and use that extra real estate to enlarge the numbers and provide choices as to what goes where. I am really hoping Garmin gives this flexibility with an upgrade soon.

Needs better interoperability with Apple ecosystem

There are a number of features that are unavailable without an accompanying Garmin watch. I have health data from my Apple watch (e.g. VO2 Max and resting heart rate), but I cannot manually enter it in the Garmin ecosystem -- frustrating. Also, every time I eject my Edge 840 from my MacBook Air, I have to force a hard reset to regain operation. It hangs during restart.
