Got this to help a friend build a caudron stirring witch kind of thing for Halloween - the motor works great for that purpose.
Has been reliable and durable to date. No issues with the operation of it yet. Very pleased at this point.
Used this for winding custom coils. It does not bog down when when you need a bit of torque. Got all the mounting brackets on Sparkfun.com also.
