How to use with Arduino Servo Library
Continuous operation servos like these are different from regular servos but still work well with the Arduino Servo library. The position is not accessible with 360 degree servos. Instead you use the Servo library to set the speed and direction of the motor. Because these are geared motors, you get more torque than you would with a regular DC motor. The 5 servos I received responded perfectly to the Arduino Servo library as described here: servo.write(0); // fast CW servo.write(180); // fast CCW servo.write(90); // stop // 0 to 90 (fast to slow) CW, front view) // 90 to 180 (slow to fast) CCW, front view) // 90 = stop If you look at the pulse widths generated for each of these settings and the operation of 360 degree servos, this is all as it should be. You should never have to cut the power to stop the servo.

Pinout Diagram Incorrect
Works fine. Diagram for pinout is incorrect in product images. Red is +, Brown is -, Orange is signal. Please update product image!

NOT a true digital servo. Might work fine for certain RC applications but nothing else
It's just a cheap analog electric motor with a mostly pointless signal wire. This means that unlike actual digital servos (which the seller claims it is) you can only control direction and speed of rotation but not make it stop at a specific angle no matter what duty cycle you use for the pwm signal. FeeTech really needs to remove "digital" from the name or at least respond to buyer inquiries in a timely manner. It's pure false advertising. I'd send them back for a refund but they're cheap and the seller has already wasted enough of my time.
