Intended for a young girl, this mouse has had its effect! The shape is very ergonomic, the perfect size to female hands, eyes light up when used ... But this is not a toy! This is a real powerful mouse, well studied (with housing for the USB relay). Only downside: the battery compartment is poorly designed: a little too big, it requires "aim" perfectly to the batteries make contact; and the little plastic strip to remove the batteries is very little solid. Otherwise, a good product at a fair price.
