I've run a set on an MX bike for two years with a couple falls, the falls will tear the grip but the surface has only worn the diamonds down. I'd actually like to replace them because the tears look bad but they aren't worn enough haha. Liked them so much, I put a set on my sport bike - they've gone 12k miles so far and only worn the diamonds down under my palm. The grip feels like the soft compound Renthal diamond grips, has the same tack and squish, they just never wear out. I kind of dig the glow in the dark color, but it does clash with probably every bike ever made if that matters to you.
