I bought this for my 4 year old daughter for her birthday. She loves rockets and I thought she would enjoy it. The pump is total junk and could not even pump enough pressure for a single flight before it broke. I spent an hour trying to fix it and the highest I've gotten the rocket to launch is a couple feet! This resulted in my daughter crying and the rocket getting thrown away. Do not buy this one!
Negative
