That mouse seemed really familiar, looked back and forth, yep its a Logitech G300s.
Mini Review after a year of use: moderately lightweight, no failures, disabled RGB so no comment, 1:1 actuation ratio, right side buttons awkward to reach for my big hands using palm grip, hand spills over the sides. For $20, its OK. Tried the G502, worth the $10-25 more IMO.
Holding it more like she did and the side buttons are much easier to reach, but then the bottom doesn't even go past the knuckles. Therefore, good choice for her female Japanese digits.
