My granddaughter had a wonderful time putting this toy together - a small amount of adult supervision was useful. She enjoyed that aspect of the gift and also loves Legos so has the patience to build things. She has used the toy continuously since then. It works well and runs on the carpet and on the wood floors. It has provided much fun for her every day since she received it. I would recommend this toy.
The Instructions were easy to understand for my 12 yr old about an hour of assembly time (easy to assemble) app was a little complicated it's on the app store so you type in the address link provided it has a lot of permission to agree my son is very pleased with this gift so it is giftable.
