    What… they aren’t spinning at high speeds and “grinding” the surface that’s on them. They only spin as quickly as they need to move the surface. Imagine a treadmill, it’s not going quicker than you are running on it, your shoes never slide on the surface, same here.

    I really don’t understand how you have misunderstood this so badly.

      If you watch MKBHD’s video, you see him spinning himself around on a chair. The chair legs are in constant contact with some part of the cone thingies while they’re rolling, which means friction, which means wear. I posted a screenshot from MKBHD’s video in another response that shows what looks like debris all over the surface of the cone rollers; the debris is not uniform and is quite clearly not part of the roller material (I put a screenshot in the reply to another comment, so I’ll just link it here), so I assumed that it was from testing the treadmill with various objects.

      As well, there was no need to be a dick about it.
