Sofia ★★★★★

The three delay elements and spacers dropped right into my E28-7T reloads with zero fit issues, and the O-rings sealed clean on the first try. Delay burn was consistent across all three, right around the 7-second mark. Nice to have spares on hand instead of ordering one at a time.

Benjamin T. ★★★★★

Ordered these for my D15-7T loads and the delays have been dead consistent flight after flight. The spacers fit snug with no rattle, and the o-rings sealed clean every time. Three in a pack is nice since I burn through them quickly.

Evelyn O. ★★★★★

Wasn't sure the delay insulators would hold up on a second flight, but they seated clean and the ejection timing was dead on with my D15-7T. Three in the pack means I'm covered for a whole weekend of launches.
