It is hard to believe, but even with my very large, gross motor hands easy to operate. Charging via the contacts on the receiver works just fine, but I can imagine that it is too narrow to very thin notebooks. Lefty should be aware that the right mouse button (preference button for left-handers) is narrower than the left to give the wheel space. The wheel has clamped on my mouse, but works fine for exchange. Shop does not have to be the mouse very often.
