Very easy to assemble, all one needs to do is follow the instructions. I would not suggest just looking at the box or you will not only have assembled it incorrectly, it would not perform as it should.
I decided to buy in pieces due to the other pricey wall tracks and being that I have a five year old singleton; he would only need a few pieces at a time to keep him happy and entertained.
I bought 2 smaller wall track sets for my grandson's 8th birthday. He LOVED them! He and his 2 brothers, ages 5 & 9, are so excited about building an entire wall set up and are asking for more sets for Christmas. Grandma and Papa will be happy to play Santa and make that wish come true! Anyone with children this age knows how rare it is to see them all playing and sharing together. The options for setting the tracks up encourage creativity and give enough variation to keep the game feeling new. Mom is happy because it is all on the wall and not on the floor getting stepped on. A winner in every way!!
My son received 5 Wall Tracks for his birthday and he LOVES them! We were able to hook this and another up together for even more cool fun Note: Not all cars are able to make the jump! He has 9 wall track cars and the ones that are too heavy or are too long, etc are not able to make the jump....He thinks this is great though and laughs every time :)
