Quick questions
Which mouse is better for small hands?
The MX Anywhere 3 is better for small hands. It is significantly smaller and lighter, making it easier to control with a fingertip grip. The MX Master 3S is larger and designed for medium to large hands, though some small-handed users still find it comfortable with a palm grip.
Can the MX Anywhere 3 work on glass?
Yes, the MX Anywhere 3 features Logitech's Darkfield sensor that tracks on virtually any surface, including glass (at least 4 mm thick). The MX Master 3S also has this capability, but its larger size makes it less convenient for travel.
Do both mice have the same scroll wheel?
Both feature the MagSpeed electromagnetic scroll wheel with auto-shift. It can switch between ratchet mode for precise line-by-line scrolling and free-spin mode for fast, frictionless scrolling. The MX Master 3S adds a dedicated horizontal scroll wheel, while the MX Anywhere 3 uses a tilt wheel for horizontal scrolling.
