Apple A1314 Wireless Keyboard

This is an excellent keyboard. Good bluetooth range, qual...ity ergonomics. I use rechargeable batteries with it, and turn it off whenever it isn't in use. I get four to six weeks of battery life that way, even though I use it 2-3 hours daily. I've bought several of these 'used' keyboards for multiple systems of my family members, and all have worked as if they were new. I highly recommend them.
