"when we got the costume, my son was excited to put it on and turn it on. Unfortunately, there wasn't a switch installed for the body. There was a place for a switch, and the battery pack was loaded, just no switch. So once we got the lights on, they just flashed, and it took a screw driver to take the batteries out to stop the flashing.
The helmet was installed with a switch, however that switch didn't work. So there was no light option for Darth Vaders mask.
After a few minutes of disappointment, my son was still excited to be Darth Vader. Dad could have saved a little money to get the "plain" Darth. I wouldn't recommend this costume."
