Q: I ordered two of these for my kids. The pump for the rocket is made so you have to hold it while pumping but there is no good way to hold it securely while pumping. There is a trigger to lock in the rocket while pumping but the trigger is in the way of holding the pump and is unsafe because a simple bump makes the rocket launch accidentally. The piston in the pump is so cheap that it bends when you push it in. The end cap on the pump chamber is not properly secured to the pump. I tried the pumps that came with both rockets. The rocket's highest flight was about 10 feet becuase the pumps were so lame.
A:
Negative
