My Countryline 12 inch auger is the third brand that I've bought. It is by far the best. In fact, for the money, it's just amazing at how well it digs. Soil that I struggled to get through, is now easy with the Countryline. Before buying it, we would use a SDS Max rotary hammer in jackhammer mode and a spade bit to get through the top layer of super hard packed red clay. Once I was down a foot, the other augers would work to some degree, but even then, sometimes I had to fill the hole with water and come back the next day. With the Coutnryline, I just drill right through the top soil. Biggest problem with it is that it drills too good and it will bury itself in seconds. You have to be super careful when using it on a 3 point hitch. With an excavator and reverse hydraulics, you will never have this problem.
