As I've used my first set of batteries in my first Beoremote One, a quick feedback to explain why I'm not happy:
On the BR1, when your batteries are becoming low, when you use a source button, instead of displaying the source name, the screen shows a big "no battery" logo and turns off. And then the screen will not display anything.
This means that all the buttons you added under the "list" or "source" button where you select a function with the screen is not usable anymore. As I'm a bit ecologically minded, I didn't change the batteries, waiting for the remote to become totally dead. But 3 months later it didn't happen, the remote was still working, only displaying a big battery logo on its display. I got fed up and changed the batteries.
The problem is that if the screen can display this big bright logo, it can still work and display your menu... I would have preferred the battery logo and then my menu to use the full capacity of my batteries. I was able to do that with the Beo4, not anymore. I think it's a bad move from B&O, a on-ecological one.
