The present invention concerns a multi-dosing detergent delivery device i ncluding a status indicator for providing an external indication of the inte rnal status of the device. The indicator comprises a first element (140) int ernal to a main housing part (100) of the device and whose position is direc tly related to the status of the device and a second element (120) external of the main housing. The second element (120) and the first element (140) ar e linked together by means of magnetic attraction. In a preferred embodiment of the invention, the first element (140) comprises a magnet and the second element (120) comprises a ferro-magnetic sphere, held within a transparent dome (110). The sphere (120) and dome (110) are mounted to the exterior of a main housing of the device and form an isolated sub-housing, whilst the mag net (140) is provided internally. Motion of the magnet (140) is translated t o motion of the sphere (120) and a static scale adjacent to the path of move ment of the sphere indicates the device status.
