After reading reviews of many, many, low priced planetariums, this one had the least negative reviews. NONE of them have really good reviews. The price wasn't bad on Overstock, so I took a chance and bought it for my 11 y.o, grandson. It came on time and looks like it's put together just fine. But when we tried it out, it just isn't what we expected. The stars can only be seen in focus if set on a dresser or table, a little closer to the ceiling and then it only shows up on a small portion of the ceiling. The stars are all the same size and it's really hard to tell if there are constellations....just not very good. I ended up returning it. I was expecting it to at least cover the ceiling with sharp focused stars, even if they weren't in constellations. I give up trying to find a starry ceiling for the grandkids....unless I get rich and can afford an expensive one. Maybe you can make one out of a nightlight and holes in black construction paper. That is about what this one is....but this one just doesn't cut it.
