Q: My boys got this for their birthday and I put it together the night before. It is quite large and impressive and my boys' friends found it their most impressive present. One friend thought it was the neatest toy he had ever seen. My sons actaually spent more time playing with their Justice League Watch Tower but this toy was next most popular. They already had all the Batman and sidekicks action figures to go with it so it worked out perfect. My sons still play with it every day. Well worth the money.
A:
Positive
