The grinding cell is about the same size as yours but the holes allow the ground bud to fall to the screen which frees up space to grind more... Like taking the screen out the grinder but better because no big chunks to regrind. You gotta shake it some to get all the bud to drop but that helps sift the kief into the bottom part. The glass part will hold a lot. That 3rd pic was a pinner for an appetizer while the yard bird grilled, so I figure you could fit quite a bit in the hopper. It even comes with a fkn cleaning kit
