I'm sure it has some redeeming value, but they way it was installed here...jeez! Five BILLION staples to attach it to the floor below, which consists of (from shallow to deep): vinyl tile, thin plywood, subfloor then subfloor again! So in total, we've been walking on:

Laminate floor on top of
underlayment on top of
luon on top of
vinyl on top of
thin plywood on top of
subfloor 1 on top of
subfloor 2!

We've decided....we're taking it down to subfloor 1 and starting anew. Good lord.
