The box arrived crumpled. I looked at it for a bit and hit the test button and it still seemed to work, so I figured it was ok. However, when my son opened the box, we found that part of the case had been crushed where those massive screws held it in the packaging. Spring. He liked it anyway. The vapor from the mouth is the best. However, he broke his arm on the first day. This thing won't last long. I wish it was more durable because otherwise he really likes it.
