[This review was collected as part of a promotion.] I had a little boy eager to use his Christmas gift. We needed these and they arrived quickly.

Just what we needed

[This review was collected as part of a promotion.] We are happy with the rocket engines. There were no "duds" and fit the rockets. We would order again.

Would order again.

[This review was collected as part of a promotion.] Love these for our rocket. Kid friendly

Easy to use
