  1. Ethan Harmon

    The soldered connections that join the wire to the motor are strong. Compared to the small coreless motors I bought from elsewhere, these wires very nice..😋 The wires of other motors break off too easily, they snap if any small amount of pressure is applied to them.

  2. Alex Stumpf

    Such small coreless dc motor with a speed of 51,000rpm, it’s amazing! Best choice for my application, really like it.
