Purchased as a gift for grandchildren. They literally jumped for joy when they first saw the planets arrive in the box. Then, when dad installed them on the ceiling of their room, they were on "cloud nine". This added decoration in their room helps them feel like they are sleeping outside among the stars and the planets...and can see the together in the sky. It's given my son the opportunity to explain more about our "small home", the earth, and how important it is to take care of it in these days where so many are in a "throw away society". He's been able to reinforce to our young 4, 6 and 8 year old grand-children that the earth is a "jewel" in the heavens and as such, we are precious, and made special among all the other creations. They are learning to do a better job of caring for their room, the house and even more responsible to Grandpa and me. It's been a gift we wish we had when our children were growing up.
