This drill bit is amazing! We have clay soil and it's usually a shame to try to dig for planting. This snail made our spring planting project so easy! I used it to dig the holes first, then I cleaned the dirt out of them, and then I machined the dirt at the bottom of the holes to be nice and loose. It works just as well as the videos show! Spend your money, you won't regret it! I am sure! As an additional note. I have sore knees so trying to stick a shovel in the ground was no longer an option for me. But I can dig a lot of holes with a drill with much less effort.
