I bought this for my son's birthday last year. I asked some children that I know which light saber was the best in terms of;
1. durability
2. continuing fun
3. realism
Universally the answer was the "Ultimte Lightsaber." I must say that the kids were right across the board. My son lovesw it and plays with it regularly. It has held up beautifully and lasted through countless battles. The ability to change the light saber based on your character allows nearly limitless capabilities to be either on the dark, or Jedhi, side.
I would definately recommend this toy to anyone with a child who loves to roleplay Star Wars and has burned through a number of lesser lightsabers.
