Which is better for travel?

The MX Anywhere 3S. It weighs 99 g, is compact, and tracks on glass, so it works on almost any surface you find.

Which is better for long workdays at a desk?

The MX Master 4 Special Edition. Its full-size shape, thumb rest and thumb wheel reduce hand movement over hours of use.

Does the MX Anywhere 3S work on glass?

Yes. Logitech rates its Darkfield-style optical sensor for glass and other tricky surfaces, which the Master also handles.

Which has more buttons?

The MX Master 4 Special Edition, with 8 buttons plus gesture controls against 6 buttons on the Anywhere 3S.

Is the Master worth stepping up to?

If you work at one desk and want a thumb wheel, more buttons and longer battery life, yes. If you carry a mouse around, its weight and size work against it.

Do both work with Mac and Windows?

Yes. Both connect over Bluetooth or the Logi Bolt receiver and use Logitech Options+ software on macOS and Windows.

Logitech MX Anywhere 3S vs Logitech MX Master 4

The MX Master 4 Special Edition is the better mouse for long desk sessions: it is larger, has a thumb wheel, 8 buttons and up to 70 days per charge. The MX Anywhere 3S is the one to carry: at 99 g it is far lighter, tracks on glass, and its quiet clicks suit shared rooms. Owners rate the Anywhere 3S very highly, and the Master line is widely praised for comfort and build, but the Master is heavy and bulky for travel.

Choose the MX Anywhere 3S if you work on the move, want a light mouse that tracks on glass and glass-like desks, and value quiet clicks.
Choose the MX Master 4 Special Edition if you sit at one desk for hours and want a full-size ergonomic shape, a thumb wheel and many programmable buttons.
