My niece loves this thing. All the writing and instructions are in Japanese but this toys makes cool noises. It would be great if they would include instructions in english. But it has a flashing light and different noises depending what code you hit. If it had instructions in English it would get 5 stars. The device is durable plastic. Even the light cover is a nice hard plastic. I wouldn't reccomended throwing it, but it's not flimsy plastic.
