Review for LEGO set 10196 Grand Carousel from Brickset
An incredible building experience — “I will say that the inner-workings of the Carousel is a Lego engineering feat. I won't go into too much detail, but when you see your creation come to life with a flip of the switch, it is a very gratifying experience to hear the little tune and see the riders going up and... More down and round and round.”
