A vibrating massager includes a housing (10), a power source (14) supported by the housing and a replaceable motor (12). The housing (10) and motor (12) are configured so that the motor may be readily replaced by a human operator without the need to replace the housing, power source, or other components. The motor (12) may be sized and configured to substitute for a conventional battery in a multi-battery device. When positioned in place of a battery in a supporting device, the motor operates to impart a vibrating motion to the supporting device.
