The motor has a good torque if provided with appropriate power. (rating changed to 5 stars)
OLD COMMENT :Torque at 12V is not impressive. (I think its < 1 N/m because it barely performs better than a nema 17 rated at 0.42 N/m)
EDIT: the driver I use (A4988) has a voltage regulator with a screw allowing to increase the voltage. Doing so increased the torque significantly (and the heat production on the driver).
So overall my previous comment on torque does not stand, since this was a matter of power supply/driver.

This is the first time I'm using a motor in a project. It's a learning experience but this motor is working great in my tests so far. I'm sure the only reason it isn't lifting more than the 1.5 pound chain I am testing with is my Arduino-based (ie current limited) power supply. I'm working on a power circuit that will allow this thing to perform great.

Difficult to find the right combo of drive voltage, current, pw, etc, but it cooks fine now.

Excellent motor. Worked perfectly for my cnc lathe project

Haven't used a lot of steppers before but as far as I can tell run smooth and fairly quiet, solid IMHO.
