FYI, a bunch of guys bought a stack of these VMAR edges, purely to see just how long it would take to break them...

These guys pushed them to the limits of aircraft durability. They didn't break.

However they didn't do anything well except stay together. It's a bit like buying a duraplane to fly unlimited IMAC, totally NOT the plane for the job.

I'd never buy VMAR again unless I wanted something I could use as a baseball bat, and they're about as heavy.
