As I unpacked it I thought to myself "that's it?" I have ordered a total of three different fluorescent products, but this has the largest and Farbinentsivsten effect. Small but powerful fits here perfectly! Although the room is dimmed has got something about it, I never thought in life when the starry sky projector stand (psc = 1) and the mobile disco light (psc = 1) far behind. I'm still an order XD A pity that there are not different levels of speed, a little would be slower perfect!
