Had to install a new mailbox post and was not looking forward to digging the post hole.  Used this, and a True Temper 69-inch post hole digging bar for a few roots.  Went 28 inches down through a bit of clay very easily and quickly.  Hardest part of the job was screwing on the handle.  The handle is made of super hard wood and it was difficult to drive the screw into the wood.  But would rather have this strong handle than a lower quality piece of wood.  Plan to use this again for preparing holes for some bare root fruit trees to be delivered in January.  Would buy again.
