The HS-425BB is offered with dual ball bearings, impact resin gears and high performance circuitry. As one of Hitec's longest running production servos, it has proven to be a durable and dependable product year after year.
The answer to this question is partially dependent on what you are using to control the servo.

With an Average Radio System:
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
