I dug 22 holes in 3 days with this. It worked WAY better than the stab and spread post hole digger that couldn't get me a clean and neat 3 1/2 foot hole without having to dig the sides of the walls to accommodate the spreading action. The only trouble I had was with roots over 1 inch in diameter or an occasional rock, but it ate up most anything else and those issues were to be expected. You need a good bar to cut the roots and dislodge some rocks, but otherwise this thing is amazing!
