Penelope L. ★★★★★

The three spacers and insulators fit perfectly with my E16-4W motors, and the delay elements cut cleanly without any crumbly mess. My first flight came down right at apogee, which is exactly what I wanted for my scratch-built rocket. Packaging was solid too, nothing rattled loose in the mail.

Miles T. ★★★★★

The included O-rings made seating the delay elements much easier than my previous kits, and the spacers let me fine-tune the timing perfectly. First flight with a G76 was flawless, and I appreciate having three in the pack for backup.

Hannah I. ★★★★★

I've been using these with my E16 motors, and the spacers make it super easy to dial in the exact delay time I need. The O-rings fit snugly and keep everything sealed tight during assembly.
