Sofia ★★★★★

Bought the 12-pack thinking I'd only use a couple, but between my two CPR flights I've already gone through four. The snap is audible and firm, so I know the ejection charge is held before I even pack the tube.

Emily ★★★★★

These caps fit so snugly that fumbling with loose tape is a thing of the past. I used two per flight with the CPR system and the retention was spot on, and having a 12-pack means I won’t run out mid-season.

Edward T. ★★★★★

Bought these for my CPR setup and the snap-on fit is reassuringly snug—no worrying about them popping off during prep. Twelve per pack means I’m fully stocked for several launches, and having two per flight is easy to keep track of. They do exactly what they’re supposed to do, nothing more.
