Received in the Philippines in just 13 days. Many Thanks. Bought for iMac 27. The reason I bought an iMac was because when I first saw MacBooks with their backlit keyboards, I bought one. It's easy to work with minimal lighting on a plane, train, home, car, etc. without disturbing others. Shocked to learn that a backlit keyboard didn't come with the iMAC and Apple isn't filling that market with a backlit keyboard. The Apple Mouse is also difficult to see in the dark, even when I'm at home. I have no problem with a wired connection since I don't put my iMac on the other side of the room. In iMAC, the popup says the keyboard is not recognized, but it's not a keyboard. I just exited the popup. The mouse has worked flawlessly on the iMac so far. Disturbing for a Logitech keyboard ordered the same day. Will update if necessary.
