Awesome helmet and chestplate makes your voice sound just like Darth Vader's! Features real electronic breathing sounds and phrases from the movie! This has never been used. The batteries that came in it for testing the unit in the store do not work anymore so I can not test the mask since it is in a box. There is no reason it shouldn’t work. This has just been sitting on a shelf in our basement for years and years. The box shows some wear.
