I had several of these as a kid and never had a problem. This one was defective out of the box! When i tried to put the rocket on the pump and lock it in place the air pump nipple snapped off and rendered the toy useless. After further inspection i found that the rocket itself was the cause. The plastic ring at the base that attaches to the pump was deformed and would not mount on the pump properly, when i slid the pump lock over the mount it started to bind and snapped the nipple off.I packaged it up and returned it.I may try some of the other models to see how they stack up.
Negative
