Ordered for smaller "bandit" rocket, contents as described, quick delivery. Very helpful to be able to order online as no other stores in our area carry these rocket engines.
Verified Purchase
They work exactly as they should. Consistently launching model rockets high in the air for my excited kids.
Verified Purchase
Great for beginner model rockets
These worked great. I think the value is a little lacking in that 3 for this price seems slightly more expensive then it should be but they worked well. There was a spare fuse in the package which is nice.
