Harper ★★★★★

The spacers included in this kit make swapping delays between my G53-10FJ loads way simpler than the old trial-and-error method. Three elements per pack means I've got spares for the whole launch weekend, and the O-rings seated cleanly without any fuss.

Ella K. ★★★★★

Picked these up for my G64-7W and the delay elements fit perfectly with the included spacers. Three in the pack means I'm set for a few launches, and the O-rings sealed up without any issues.

Adam J. ★★★★★

Wasn't sure I'd notice a difference swapping these into my G64-7W builds, but the delay timing has been dead consistent across all three flights. The little spacers make seating everything a lot less fiddly than the old setup I was running.
