@pawv @nblr @NanoRaptor Holy shit, this is *real*! I was looking for a smoking gun proving that it's fake, but instead I found this manual for the Logitech MK255 TM250G Wireless Keyboard and Mouse Combo, which I have backed up for posterity: https://drive.google.com/file/d/17qEFUvDQIuG-vbvSzILhUjwDPJmZQB7Y/view?usp=sharing Anyway, I am excited to see if anyone has a photo of the rare cruciform AAa battery that everyone forgot was briefly available for this model, but sadly not compatible with the side-by-side AAa standard that was chosen by most other manufacturers.
