Exactly what I wanted!
The media could not be loaded. Bought a dual rocket kit for me and my son to build. Perfect but needed supplies and motors. Everything was perfect and now we're launching again soon!

It works, fits rocket snug and removed easily.
Rocket flew to expected height for description, second phase blew out parachute without failure. No issues removing motor from rocket when burnt out. Electric match worked first try, plug held match secure.

Awesome!
Exactly what I used as a kid! They don't come with recovery wadding anymore, but the description made no mention that it'd be included. So plan accordingly!Shipping does take much longer than typical Amazon prime shipping; as expected. But comes when expected, and well packaged.Will be a regular buyer from now on.

Buyer beware
They did not ignite not the first time I used motors. I had to use a torch to get it to fire
