I like this Hop Up because if you think of how much work the servo saver piece does in steering your vehicle then you'll know its important. Usually for beginners if you use the original plastic ones and you crash and hit the wall alot, then it can bend, crack or warpped. Having a aluminum one insure all those dont happen and its much smoother when steering. I also like how it comes with the optional piece to change the height of the steering rod. Overall a great addition to your car.
