I agree w/ Wayne I use my stone age age bend the bar ones(1/4" 3/8" and 1/2" versions) far more(100:1) than my fancy electronic and click ones. The only down side is that my old eyes have difficulty reading them w/o glasses. But the same can be said about reading anything(including the dash board in my Audi
but not the 911
Thank god for small favors!)
