Next to pointless! My 7 year old, who loves Lego Star Wars game, used it for 5 seconds, took it off, and said "No thanks, Daddy"! Yes you fit your wii controller to the light saber and switch it on, great! But only to find out that you can no longer use the 'pointing' of the remote! My son swings the control to operate the character on screen (fighting with light saber for example) but cannot do that any more with this attached, can only use the buttons instead. I thought the whole point of wii was the playability and the alternative to pressing buttons. My recommendation - find a saber that doesn't stop the remote operating!
