Robert ★★★★★

I was glad to see the spacers included, that saved me a trip to the hobby shop. These delay elements fit perfectly with my D24-7T motors and the O-rings sealed just right on the first try.

Jason ★★★★★

Having the O-rings and insulators included saved me a trip to the hobby shop for a small project. The spacers let me get the delay just right for my rocket's weight.

Ryan I. ★★★★★

The three delay elements gave me plenty of room to test different configurations, and the included O-rings and insulators saved me from having to source parts separately. My first flight with a D24-7T motor had a perfect ejection charge.
