Is the MX Master 4 worth it over a basic wireless mouse?

If you work at a desk for hours and want a thumb wheel, multi-device switching and app-specific buttons, the extra features earn their place. For casual or travel use, a smaller, lighter mouse is easier to live with.

How does it compare with earlier MX Master models?

It carries over the same ergonomic shape, thumb rest and side wheel that made the line popular. Buyers upgrading mainly gain the latest sensor and connectivity rather than a new shape.

Does it work with a Mac?

Yes. It works with macOS as well as Windows and Linux, and the custom buttons are configured through Logitech's software on each platform.

Can I use it with more than one computer?

Yes. It pairs with multiple devices and switches between them with a button, so one mouse can serve a desktop and a laptop.

Is it suitable for small hands?

It is a large, palm-filling mouse, so people with small hands often find it too big. Those with medium to large right hands get the most from the shape.
