I have the keyboard mouse, battery charger and 6 rechargeable batteries from a 2011 imac. The batteries were fully charged after last use but have been sitting a couple years. They may not work, but when i put them in the keyboard the green light flashes, I believe because there is no device to pair it to. Will work with any mac w/bluetooth. The return key popped out on one side. This little scotch tape fix has worked for years, see in pic 4. Otherwise all good.
45 for keyboard and charger/batteries
35 for mouse and charger/batteries
75 for all
please reply with a phone number and sound like a real person
