Stomp Rocket® Super High Performance Refill has been reviewed 12 times with an average rating of 4.58
Darn, I hoped these different level performance rockets were perhaps interchangeable on the launcher but, alas, they are not. You must have the specific rocket for the specific rocket launcher. They other replacements seem a bit costly though so I will have to order a super high performance launcher. My grandson & friends do have a lot of fun with it but at 8-9 years old they want them to go even further.
