Yesterday these devices arrived for me. I've got to admit, the new mouse feels more dense, but I like it. The clicks are louder and it affirms that I am actually making an action. I loved the setup, I did the automatic identification by plugging the devices USB into my MacBook Pro, and it was instantaneous to identify. I will say this, I let my Magic Keyboard charge for 5 hours and it remained at 97%, I then unplugged the device, shut off my MBP and this morning had it charge for 2 hours and still 97%. Any ideas why the Keyboard won't hit 100%?
