I've been using .5 mm Quicker-Clickers for more than ten years, and I adore them. I like to press very hard when I write, and the Quicker-Clicker withstands the pressure beautifully, holding the lead firmly in place and producing a dark, sharp line.
The one down side is that the erasers, which work very well at first, don't really stay in place once you've worn them down once and try to "move them up" within the holder. Also, the little plastic cap that comes on the eraser seems utterly unnecessary.
On the whole, though, these are my favorite pencils in the world. Like the reviewer before me, I kind of freak out whenever I can't find my Quicker-Clicker.
