Rated 4 out of 5★ by Just1las Lot's of fun and stretches his brain! This was a Christmas gift for my 9 year old son. He's not a builder particularly unless what you build can actually be played with afterwards. He likes the game Mouse Trap so when I saw this Contraption Lab I thought maybe it would be good. He LOVES it. It doesn't take long to put together and then you get to watch what all happens as the ball(s) go through.All in all it works very well. Some of the heavier pieces have a little trouble staying straight and sometimes the ball will bounce off the track, but it just takes a little adjusting to get it going. I mean that's what a contraption's all about, right? Getting it adjusted just right so it does what you want it to do.Lot's of fun and stretches his brain! 01/01/2013
