"Works Great"
Rocketman (Lebanon)
I have 2 rockets with this on. I never had any problems for either of them one had 12 launches into it and the other one had 3.

 
"Great for new builds"

Time to get rid of those pesky engine hooks with these retainers!

 
"Simple Yet Effective"
Mr. Northport (Northport, WA)
I really like these retainer ring setups as they make engine mounts simpler to put together. They also look better cosmetically, better finished look, as you don't have the middle finger sticking out of the end. It also makes it far easier to build two stage rockets.
