We bought this for our daughter who is interested in ASTRONOMY (!) and wished we hadn't. It is of poor quality, when you press the button to start the thing rotating you get a short, tinny commentary about ASTROLOGY (!!). It comes with a CD which has PC software on it. Nowhere on the box or in the booklet does it give minimum specs for the computer and as a Mac user it is useless. The box gives the impression that it is for budding astronomers but the commentary and the booklet devote themselves to what can best be described as populist nonsense. The starscape projected on the walls and ceiling is blurred unless the toy is held less than 60cm from the ceiling (which is OK for me. I'm 1.83m tall!) but not a lot of use to a 7 year-old.
I can think of nothing to recommend this and suggest to all that you steer clear of this one.
