I have a wide assortment of Sears tools that I have purchased over a lifetime. When buying the power tools, I always bought the top of the line. I have owned tools like my 12" table saw, 10" radial arm saw, 7 1/2" circular saw, 3/8 and 1/2" air rachets, side grinder, die grinder, and many others for almost 40 years and never had a serious problem. I use my tools hard, but don't abuse them.
I am not crazy about the wrenches because I always thought they were a sloppy fit. I have picked up some over the years and find that there are even some cheap overseas wrenches that fit and work better. I have never broken a Craftsman wrench, but I have never used them for the difficult jobs because of the looseness of the fit. ( I prefer 6 point wrenches rather than the 12 point, and these were not available in the Craftsman line for many years).
I have no regrets about the Craftsman tools I have purchased, and think it is more about how we take care of our tools.
