Our 3 year old son loves the profession and the work of Bob the Builder and provides them in everyday life often after. The audio books we bought him as bedtime stories, in addition to the reading to fall asleep. Works very well and he switcht between 3 selection CD's every day back and forth. Our son is happy with his Bob and so are we. The voices are pleasant and not too flashy. The sounds well simulated, so nice stories have arisen.
