My sons are ages 5 and 2 respectively. They are very active, creative, and innovative little boys. Our oldest son loves to play with Legos, build and create. So, when we saw the Kinect kit for $10 during the holidays, we thought what a perfect gift for Santa to leave under the tree. Needless to say, our son has created a boat, bike, motorcycle etc. The instructions could be challenging for some kids, but after working with his dad on the first project, he needed no supervision. Excellent purchase!! We highly recommend it!
