They work. They're not the best, but they're not the worst either. I used some of them for years; I gradually upgraded to others, and then finally just systematically eliminated them from my tools. You have to recognize also that the quality varied over the years, ebbing and flowing with the contractor making them and sometimes within the run from a manufacturer. That explains a lot of the varied experience people have had with them.
The problems I have had with them:
The combination wrenches have too much bevel on the box end; you lose up to 1/8" of holding capacity on the nut. Thin nuts, that's a problem. The DBE longs, I have had bend and twist. I have Proto and SO, they have not done so under the same usage. I have also found that the Craftsman systematically round off nuts/bolt heads easier than my better wrenches. Some of that is the bevel, I also believe some is wrench broach geometry. Subtle, but long use has verified that. I have also had some Cobinations and some DBE that had absurdly thick box ends that created clearance problems. The DBE's that I really liked and had a set of for years did not, but they were the ones that also bent. So, thicker wrenches equated to more strength; but caused clearance problems. You couildn't win. I replaced them with Proto that were both thin AND strong, and have been much more satisfied with them.
I had one of the coveted Vee selector switch flex head ratchets that I liked;but it failed because the pawls/mechanism weren't strong enough. When it was warranted out, it was replaced by a junky one that randomly switched directions when you were pulling on it, causing you to slip and damage your hands. That was the final straw that made me go to all better ratchets. I had some Williams, SK, and Proto already and one Snap-on, so it was easy to know where to turn to for better.
They're okay general use wrenches; just use them within their capabilities. When they start feeling that they're springing, slipping, or bending, stop pulling because they probably will fail you. The ratchets are less useful, some are better than others, but don't trust them for heavy pulling. A lot of people never push them to their limits; for those uses they are very good wrenches and ratchets.
I personally have never had a problem with the feel on my hands; I prefer others, but don't mind the feel of the raised panels.
