I only wish I had discovered this two years ago? It's such an easy way to loosen the soil when trying to plant. I've found the smaller to be much more efficient and versatile than the larger. I was delighted to read a warning in the reviews to hold the drill with both hands in case you catch the route and the drill pulls. I can see how easy it is for you to spray on your wrist if you're not careful. Be warned, be careful, it's been great to use with no complications, it makes planting flowers a breeze!
