Ellie ★★★★★

Finally got these for my D24 motors and the delay spacers let me fine-tune the ejection timing exactly where I wanted it. Much cleaner assembly than my first attempt with a different kit.

Hannah A. ★★★★★

The O-rings fit perfectly, making assembly straightforward. I appreciate having all the spacers and insulators included in this three-pack for multiple builds.

Ruby ★★★★☆

I've used these delay elements with my D24 motors and they worked perfectly for adjusting ejection timing. The included o-rings and insulators made assembly straightforward, though I wish there were clearer instructions for the spacer stack.
