Great plasma ball for a relatively low price. She now works for many months, where she was often turned on, still properly. The advertised clapping or music feature will only work very very limited, it works only with very very loud Dubstep music .. :) In addition, an unpleasant odor develop if you have the ball for too long, as a permanent decoration is therefore not really suitable, rather than funny, nostalgic gimmick in between.
