I've had mine for a number of years and have found them to right handy for working on PE for my aircraft builds. Good for quick simple folds. I recommend them.
I'd like to second that.
On the bending jigs (the Bug and such), I think for bigger and more complex bends I'd agree with Joe and Jack. That said, I haven't touched mine for years, favoring a straight edge razor blade and 6" machinists scale for a straightedge.
However, my PE work has been fairly basic and not involving some of the complex PE found in ships and stuff, so no way I'm throwing stones at the bending jigs.
My go to tools for PE are my tamiya PE diamond file, Tamiya PE pliers, the aforementioned razor blade and straightedge scale and glass cover from an old halogen work light for use as a work surface.
