New Hinges or Hinge repair kit?

My door hinges are worn and I have to lift the door to shut it... I thought about buying new hinges until I saw a door hinge repair kit. Dorman makes a door hinge repair kit for much cheaper than a whole new hinge.

Have any of you guys repaired your door hinge with one of these kits? I wonder how hard it is and if it is worth it vs. buying a whole new door hinge.
