It's a cute fun toy, but the sides are too tough for my 4 year old to open. I had a difficult time with it and broke a fingernail trying. The tracks are also fairly tough for small fingers to snap together... but they do stay once set up! The instruction diagrams are poor quality, very blurry, and in black and white- making sticker placement somewhat annoying. It is kind of small and cheap looking overall. Also, it does not connect even closely with name brand car tracks so adding to it does not work.
