This was a stocking stuffer for my son. He enjoyed making the robots but they ended up taken apart in the Lego bin very quickly. I am not sure how to rectify this situation. We pay a bit more for these unique sets but many of them simply don't have the lasting play value of others. The Star Wars sets have stayed together through years of play, as have the Batman sets, others just don't hold the same interest from my child. If you think they same will happen then it may be better just to get the big boxes of Lego's for the same price as this set.
