This was given to me a few years ago and I used it for maybe 30-60 minutes but eventually started to feel nauseous and put it away. Everything is in practically brand new condition, however, the box has a few pokes in it (see picture). I'm not sure what this is from but I think it happened during a recent move. The holes are only in the white outer sleeve and whatever poked it didn't make it through to the main brown box.
