Bought to plant a bouquet of flower bulbs (surprise!) It works well but not as well as I would like and I don't plan on using it to keep using I'll stick with an old fashioned shovel Pros: Easy to attach to the drill Finishing was not a major issue I cared about Can run fast if you don't have rocky terrain Cons: Rocks can be an issue and this can be ideal for an area where you won't encounter them. For example a fully manicured yard, raised bed, etc. I haven't used an insanely powerful drill bit, but I've encountered enough rock to be unwieldy (and. don't see r big) became. It seemed like it was just kicking up dirt everywhere instead of keeping it in a neater pile for refills, but maybe I turned on the drill too quickly? If you take care of the worms (hey, I'm trying to save them), they'll likely be blown to bits. At least with a shovel, I might have a better chance of salvaging a few and holding a tidier pile of dirt.
