Overview: Good low-range (strength and current) stepper.
Packaging: Motor was surrounded w/ protective foam padding, inside light-wt cardboard.
Nice addition: A product datasheet was included.
Functionality: It worked as expected. 200 steps per rev. It was not noisy: I tested at 75rpm (12v, 50% duty cycle, current limited at 200mA).
Electrical specs: Each coil was 30.0 ohm, matching the datasheet. At 12v input, this resistance is consistent w/ a max output of 400mA (Ohm's law), matching the datasheet's current max.
