My 10 y.o. daughter dreamed about this laboratory and read all on-line reviews about this toy. When she got it, she was not disappointed, she spent the rest of a day creating very adorable Monsters.
Bought it for my 4 yr old. She loves it and keeps her very entertained. The only issues with it is it seems to leak, I always put a towel under it and it is a little hard for her to push down all the way but older kids shouldn't have a problem with it. With all the extras out there for it the creativity is endless.
