Accessory specialist Kensington has lent its support to charity Breast Cancer Campaign by offering ten per cent of the money it makes selling its new pink Si750 wireless optical mouse.

Aimed at notebook users, the Si750 comes with a travelling pouch, and the USB receiver tucks safely into a bay built into the back of the mouse. Docking the receiver automatically switches the mouse off.

Kensington claimed the device will operate for up to six months on a single AA battery.

The special edition Si750 goes on sale next month for £40 through Currys and PC World stores.
