I have had Eagle AXS for a couple of weeks and it is, in my opinion, as game changing as the original Di2. Easy to set up and adjust. Low shifter effort- just bump one of the paddles. Consistent and reliable shifts. Faster shifts than mechanical especially to bigger cogs. So far, batter life is over six hours for me. Probably closer to 8 hours. I carry a "just-in-case" spare battery with my tools. Yes, the price is high. It will be more affordable when it is available as an upgrade with just derailleur and shifter. One note- I have seen mention in the press that the shifter has three buttons. Not really. It has two actual buttons. However, the paddle is shaped so that you can press either the upper part of the paddle or the bump on the front and either one will press the upper button (usually upshift). The bottom part of the paddle pushes the other button. I would love three buttons so I could control my dropper as well. But the current shifter can't do that.
