I wantid to do it because you make it and have it for yourself and you can make your own choises. You have to put all cines (kinds) of different stuff on it.
You have to put a emiter (emitter) on it and the handall and the lite buton.
Allsow you have to put the noise in it.
Its awsome!
My kids love the build your own light saber ! They like how you can design it yourself.
