A cast iron weight like this one is handy for tasks like:
-keeping bread flat on the skillet so your sandwich cooks evenly
-cooking meats on both sides, by preheating the weight
-pressing extra fat out of hamburgers

A common question with grill presses is whether they can be used in a covered grill. Since the press provides even heat distribution on the top of the item you're cooking, there isn't really a benefit to closing the grill cover.
