MSE-6
Rebaxan Columni's general purpose droid, the MSE-6 was heavily advertised and promoted in over 400 sectors. While many trillions were sold throughout the galaxy, billions were returned because their emissions were similar to those of various species of pests. The galaxy generally detested the little droids, and Rebaxan faced bankruptcy. The company ended up selling them to the Empire at a small loss. The Empire used these small, 10-inch-tall droids to fill the need for cheap, reliable labor. These boxy little droids, known as Mouse Droids because of their size, were easily programmed to perform class-three tasks, such as message delivery, in nearly every Imperial outpost, including the Death Star.
