What we can tell you

The larger-bodied version of the same six-button quiet mouse, sold on hand support rather than on features: the L in the name is the size. Adjustable sensitivity, Bluetooth or a receiver, and a battery figure measured in years. No remapping software is published for it on the sources we could read, which is the one real gap against its siblings.

What the specifications favour

  • A larger shell for larger hands
  • Silent clicks with six buttons
  • A multi-year AA battery figure across two connection types

What to check before you buy

  • No remapping software is published for it
  • Right-handed only
