It is practical for lefties that the right and left mouse buttons can be swapped. The software is still in beta, but it already works very well. Also, among other things, the mouse's buttons can be configured in the new Logi Options+ software and its function can be individualized for different applications. This doesn't work quite as smoothly as on Logi's more expensive mice, but it is a nice feature. This SmartWheel can be used for fast scrolling by a firmer nudge.

Logitech relies on recycled plastic, but its share differs significantly depending on the color variant.
