    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:

    - high torque
    - Great precision
    - Driver works perfectly with this stepper motor
    -Drivers available in standard Arduino library
    - Sample code available at http://arduino-info.wikispaces.com/SmallSteppers as described in one of the forum threads of DXmoocow
    -unipolar stepper motor, does not require H-bridge.

    Cons:

    -Very low rotation because of high torque. Needs big gear(large radius) to be placed on shaft for projects that require large displacements (2*pi*r).
    - Confusing what kind of gear to purchase for beginner to be placed on shaft.
    -Requires female to male/female wires!(male wires in Arduino, female wires in ULN2003 driver).

    OtherThoughts:

    Although the codes for this motor are confusing, I have experimentally determined that this stepper motor needs 1024 steps for a full rotation. Setting the steps/revolution at 1024 and commanding it to make 1024 steps results in exactly 1 revolution, doing this with other values will not work as the motor shaft will have an offset.

    Bottomline:

    Great device. You will need extra stuff to make it work though. Don't forget to order male/female wires and some sort of gear for the shaft if you want to use it to drive something else.
