Hi there - I bought the MX keyboard in January and up until about a month ago it worked perfectly - lasting a few months on a wireless charge. Then - something changed and now I get 2-3 days. I noticed the other night, even when the Mac Mini was turned off, every 10-20 sec the keyboard would light up and the computer button assigned (2) would blink - like it was constantly searching for a connection. Please advise, cheers. Marc
