Doesn't completely replace a drill, but does a little more than I expected. I keep it at home with my small tool box and most of the time I don't have to take my drill out of the garage for repairs or chores. I drilled holes for the TV and then screwed them into those holes, built a closet, replaced several outlets, and a bunch of other work. It's definitely an easy task and if you overdo it it will fall hard and stay put, but if you treat it right you'll be amazed at what you can do with it.
