We bought this as a gift for our grandson. We put it together to test it out. Our ceilings are 30 feet. It shot right up to the top! We had fun playing with it. Definitely going to be a fun summertime game to play with outside away from houses. Easy to set up. Very little pressure required to launch rocket. Even my smallest grandson will be able to eject it high in the air. Great for kids to interact and have some friendly competition.
