So this is a great little auger if you have absolutely no problem with soft soil. However, if you have even the tiniest little rocks, clay, or debris in his way, he doesn't like wading through them. The tip of mine got stuck in the clay the entire time and the blade couldn't penetrate because of the 1.5 inch gap between the tip and the blade. Only need teeth on top! Overall great quality, great width and fits most drill bits. Improvement Tip: You need teeth to be able to smash through obstacles to the desired depth.
