I bought this item and Cyclone for my two grandchildren for Christmas. Ziggle is very durable, with an all-metal frame. Wheels appear to be of good quality. The five-year-old had no problems riding. Not sure if a 3 year old is big enough to ride. This device should last a long time. Bought a second unit without hesitation. It was very easy to assemble. The illustrations show how the block is assembled.
