My son kept on seeing these commercials for the icoaster over Christmas last year. I refused to pay $79.99 for the set; which was the price I saw it in Walmart for. While in Costco buying finger foods, I spotted the iCoaster end-of-aisle display and it was on sale to boot!
The iCoaster is a building set. Using towers of varying heights and tracks, you build a roller coaster that you can roll a metal ball through. The iCoaster comes with 78 pieces. There are instructions for 10 different setups provided in the kit, including steps and pictures so you know which parts the steps are refering to. This is a new and improved edition of the iCoaster as it also includes 7 hyper stunt configuration instructions as well. It also has a main control box that you can connect an MP3 player to so you can play music while running the iCoaster. The control box also has its own built in music including 10 songs and drum beat.
Since my son got this last Christmas I could count on one hand the number of times he's played with it. However, when we have played with it, it was a lot of fun!
