We have this and the triceratops now, and both are firm favourite with my 3 yr old and my 1 yr old.
This is a cute little Stegosaurus who, when the button on top is pressed, makes cute little dino roars. His mouth also moves and he does the cutest little bum wiggle.
As for educational value, past 'this is a stegosaurus' I'm not sure there really is one but my kids love him and he is certainly durable.
If you have a youngster who likes dinosaurs this will be ideal, not sure that kids over 5 or 6 would enjoy him as much though.
A very good value little dinosaur toy.
