Great building toy that will last many years.Lots of pieces which is great so you are only limited by your imagination.Comes with a few tools: drill, screwdriver, and wrench.The manual has 10 different models you can build. Instructions are decent, but could be improved to show a few more steps and different angles.Everything is good quality.Baby is a bit young to do this on his own but he can use the drill and screwdriver so we have fun building the robots together. I put the pieces together and he drills the screws. Sometimes he just combines parts or takes apart things I put together. Its still a great way for him to work on his coordination and motor skills
