@hazardwarning I bought a Logitech mouse a few years ago that goes for at least a year on a pair of AA alkalines. This was the Mac version, white in colour & $10 cheaper than the black windows version. The Windows one has a button with the Windows logo on it, the same button on the Mac one is unmarked.
Then I lost the thing, couldn’t find it anywhere so I replaced it with the Windows one.
I found the white one only 7 hours ago, under a little-used computer backpack bag.
It’s on it’s 2nd set of batteries & they’re still OK.
