Mine arrived crushed because there's no package padding (should be double boxed).  I fixed it myself because I didn't want to return it, by bending it back into shape (it's sort of flimsy, so it wasn't hard).  But, it's too loud for the bedroom even on low.  And, it smells of an oil/electrical smell when it is turned on, yuck.  I have it turned on outside to try to work out the smell (no, it's not rubbing or smoking or anything).
