Finally got to use these!

Oh wow, I'm not quite sure if I can adequately describe what a difference this makes when cooking steaks on the grill, but it seasons meat so evenly and perfectly, while providing a clean cooking surface.  It actually DID make a pretty significant difference to the grilling experience.

Protip; Pat your meat completely dry.  The water on meat prevents seasoning from penetrating.  I used a bit of olive oil to prevent sticking and it was spectacular.  It's also a great conversation starter when you're grilling with friends!
