Very small and durable. Comes with plenty of "arms" and screws to hold in place. The wires are long enough to not be a problem.
None really. Just take into consideration it is a micro-servo, so it is not very powerful. It's good for moving small parts, not for heavy lifting.
Remember this isn't a continuous rotation servo, it is a common servo with a rotation limit. Its rotation angle is a bit more than 180º, I'd say. Also easy to use, as are all servos: red is power, black is ground, orange is signal.
