Ok, for years I've been meaning to get one of those handy-dandy string winders, imagining whipping the strings off in a fraction of the time. Finally I got one! Only one problem: it's a total pain in the a**! It won't stay on the tuners when I'm turning it, just slides of after a couple turns. I got the one from Gollihur, the kind where you can remove the crank and use a drill-driver as well. Did I get the wrong one, or are they all like this? Is it me?
