Won't secure to base.
My niece was really excited about this for Christmas. They got it all put together, but she said it easily comes disconnected from the base and just falls off. They can't get it to secure very well to the base.

Poor results.
The rocket would not launch more then three feet unto the air on numeral tries and the parts that snapped together on the hydraulic arm did not fit without being trimmed.
