  1. Bernard McNamara

    These 4mm micro coreless dc motors are just the right size for my project. They have plenty of power and run smoothly, low noise. The price is also reasonable.🙂

  2. Mandy Thompson

    Really tiny coreless dc motor, 4mm diameter, low start voltage, high rpm and have no noise, the output shaft is very thin but strong enough to drive our small device.
