Any vibration tool without a "jackhammer" setting is useless.
If they vibrate the thing, it will wear off enough grains (1 millimeter or less) to go through the screen. They don’t need to pulverize the stuff. If they did, they would have built in a crusher.
Do you really think they didn’t try this thing out on as many different kinds of soil as they could find? Do you think they didn’t consult soil experts to see what they thought?
