What still earns its place is the connection. One owner who has stopped caring about specs and shapes, since everything is similar now, says the deciding factor is which wireless feels like a cable, and puts Logitech ahead on that. Another who left for a vertical mouse was happy with the switch but still missed how the Superlight handled its dongle.
What people adjust to, or do not, is the feel in the hand over time. One owner describes a familiar arc: a new mouse feels like better aim at first, then after a couple of months it grows less comfortable, and the Superlight followed the same arc as their other mice. Another liked the ergonomics but got cramping, and wanted it lighter than it is; they have since moved to a lighter mouse they find more comfortable. One owner comparing it to a cheaper mouse at a lower weight said the two felt equal in quality, which cuts both ways: the Superlight holds its standard, but the standard is no longer rare.
