Harper ★★★★★

The three delay spacers seated snugly into the motor casing without any play, and the included O-rings gave me confidence I wouldn't get a leak. Saved me from having to order separate parts for my scratch-built rocket project.

David H. ★★★★★

These spacers fit perfectly with my G76 motors, and the o-rings made sealing the delay elements straightforward. Exactly what I needed for consistent flight timing.

Abigail G. ★★★★★

My son's rocket kit needed these for the G76-7G motors, and the fact that you get three full delay elements plus the O-rings and insulators in one pack is a lifesaver for a hobbyist who tends to lose tiny parts. The spacers were clearly labeled in the bag, so assembly went smoothly on the first try.
