I first bought my nephew the Charlie Monkey book from the series and he LOVED it. My sis had to read it to him every morning. So, for his birthday I decided to get him the other three books, which included Rusty Robot. The first copy I received was missing the googly eyes, and the last page didn't light up and play music (on of the selling points for my nephew). I exchanged it for another copy, which simply didn't light up or make music. I exchanged that one for my third copy, which work the way it should. I will say that Overstock was great in processing the exchange and I am a satisfied customer. The other 2 books from the series I also ordered from Overstock, and they arrived in perfect condition, so I think I just had a streak of bad luck.
