Is this a good way to Clamp a Rotation?

Question

The code below works fine but somehow when I try to rotate the object again when it reaches the minClamp and the maxClamp it seems somehow delay when I pressed a key to rotate it.

     public float minClamp = 0.0f; 
     public float maxClamp = 90f;
 public float speed = 5.0f;
 private float zRotation = 0.0f;

 void Update () 
 {
     zRotation -= Input.GetAxis ("Horizontal") * speed;
     transform.eulerAngles = new Vector3(0.0f, 0.0f, Mathf.Clamp(zRotation, minClamp,     maxClamp));
 }

You want to clamp the zRotation value first, otherwise it'll keep accumulating while you hold the axis:

 void Update () 
  {
      zRotation = Mathf.Clamp(zRotation - Input.GetAxis ("Horizontal") * speed, minClamp, maxClamp);
      transform.eulerAngles = new Vector3(0.0f, 0.0f, zRotation);
  }
