The touch screen is not very responsive-sometimes I have to touch the screen many time for it to respond. The HR monitor is better than the old one. I do like the auto upload feature via wifi so my rides get to Garmin Connect and Strava before I even get into the house.
It took about four attempts to get it paired with my 820, despite doing the exact same thing each time. Once it did pair, it works perfectly and makes for safer & more convenient riding by not having to take hand off the hoods to switch screens.
Very easy to install and flawless link with a Garmin Edge 1000. This set was installed on a second bike. The firdt bike got over a year out of the battery.
The product it self is very nice but you HAVE to have WiFi for it to work properly. I thought I could just bluetooth the information to my phone and it would update. However it does NOT. Now we have a high dollar set of scales that do not link any of our information.
