Do I need it? No, I'm not working around a running MRI. Did I want it? Heck yeah! Just don't tell my wife how much I spent for it. It did turn a few heads amongst my peers, though, with the most heard "wow, it's so light!" The quality is outstanding. I can't put it down, and it has become a new fidget toy for me. Yes, it has been used a few times. As light as it is, it's no problem to carry it around in your back pocket for whatever comes up. This thing, along with many of my County Comm purchases, will be passed down, after I'm done with this world. I can imagine it becoming a family heirloom.
