I always had an old AFA deburring tool that eventually broke and wouldn't hold the deburring tip anymore. And when I needed a new one, I saw this one, and the expansion part is extremely useful when creating titles or RPG cells. You also get a variety of interchangeable tips for different types of metals and plastics. I've had it for a few months now and tested it myself, well it holds up very well even when fully stretched, with some tension to get into those hard to reach places, it hasn't let me down. For the price and what you get, and a tool that saves you time and doesn't have to worry about breakage, that's a huge plus in my line of work.
