Great little tool. Powerful and effective in etching and egg blowing crafts. I did buy additional drill heads to make this more universally applicable to my craft needs. Holding the drill and turning it on and off are difficult while multi-tasking in craft work so I cannot give it 5 stars. Also, it is difficult to adjust the changing drill heads due to the very deep and small screw that is the sole means of holding the drill heads in place. A good starter tool for craft jobs.
