Worked perfectly on Wednesday. As my HRM battery died, I was toggling through other screens while riding. The actual buttons are so much better than touch screen. Such a positive engagement when you click... not worries about gloves. I keep it on the bike and don't bother charging until every other ride or so. Supposed 17 hour battery life from what I recall. The climbing screen is kind of fun. The display is so crisp that you don't have to look at it... I just keep it in my peripheral vision.
