Is the Rhino Pad pool liner pad worth it for an above ground pool?

Here's the bit the listing buries: a pool liner doesn't usually fail from one dramatic puncture, it fails from months of quiet friction against whatever's underneath it, water shifting weight around, grinding the liner into the same small rock over and over until it wears through. The pad's job is to break that contact entirely. It's a thick, seamless layer of padding cut precisely to your pool's round shape, so there's no bunching or exposed edge for debris to catch on. Underneath that cushioning, it also acts as a vapor barrier, which matters more than people expect: ground moisture rising up through dirt or grass will corrode the metal frame components of your pool over years, and the pad blocks that moisture from ever reaching them. It works on concrete, decks, dirt or grass, because the point isn't the surface, it's putting an inert layer between your liner and everything that surface might be hiding. And because it's precut and trimmable, you're not wrestling a tarp into a circle, you're laying down something that already fits.
