As a pro sound engineer for a number of years, Im kind of amazed at what value is in a cheap, no-name package like this. So i retract my 1 star rating. Im constantly reaching down to re-center it. Does exactly what is supposed to do. Complied by letters and records left behind, author Steven Snyder, son of the pilot, Howard Synder, recounts the exploits of the crew from their family background, to training to the fiery crash that caused them to parachute and survive in enemy territory. (That was expected) pieces were all inside. My favorite is the tri-level tips but they all fit. Never came undone. For me, these are great! The fact that they are adjustable is what makes the difference, otherwise, my heels would be popping out with each step.
