While I kind of agree with Elroy, here's the problem... IF I am using an open end wrench, it is out of necessity due to limited space or whatever. Of course it's my fault if I yank on a rounded bolt and strip the hell out it. But, if I had to take the time to find a different solution every time I came across a worn out bolt, I'm sure I'd go broke.
The problem with the raised panels, in my experience, is they are just much more prone to what Elroy described than most quality wrenches. Harbor freight wrenches probably work great too on a perfect fitting fastener. Since there are too many times where fasteners aren't perfect, I'd rather buy wrenches that can handle it.
As many people have done, I started out with a basic set of raised panels and upgraded when I could afford to. They're an awesome value and have their place, but they are NOT great wrenches. Just my opinion
