I already threw away the packaging, well, oooooooooooooooooooo. But it's pretty much useless. Digging a hole in the grass? Grass almost doesn't touch. Digging in unploughed earth? Small indentation. Digging in the already used dirt? Works well. Probably saves a few seconds per hole compared to a hand shovel. For the record, I use it with a Dewalt screwdriver that can drill through brick, so I don't have enough power. I'll update if I figure out a trick to actually make it work.
