I wasn't sure what the one reviewer meant when they described the saw as 2 dimensional. But after receiving it I understand. It is indeed a 3d product, as opposed to say a flat piece of paper. But it is not full chainsaw width. Not even close. It is only 2, maybe 3 inches thick.
But that doesn't matter. It's still so much fun! The scream is kind of quiet. But my 10 year old and I have no complaints!
