Scarlett ★★★★★

Used these delay spacers on my F52-11T build and they cut the burn time perfectly for a lower altitude flight. The O-rings sealed well with no gas blow-by, which was my main worry. Three kits in a pack is generous for the price.

Timothy T. ★★★★★

The O-rings fit snugly on my G64 motor, and having three sets in one pack makes it easy to keep spare parts ready for the next launch.

Jason ★★★★★

I've used these with both the F52 and G64 motors, and the O-rings fit perfectly without any leaks. The spacers let me dial in the exact ejection timing I needed for my heavier rocket build.
