The Craftsman locking adjustable wrenches have solved the lifelong problem of using adjustable wrenches. You know how you use the old ones, put on the nut and tighten, turn, then have to keep re tightening and re adjusting through out the use. SO ANNOYING. Finally, no longer! You set it, lock it, and get your work done! Thank you!

This is an adjustable first and vise grip second (not the other way around). What I mean is that the adjustable does the tightening around a fastener, the vise action just makes it so the adjustable action doesn't slip. The vise action doesn't do further tightening around the fastener itself. Otherwise the tool performs okay. I returned though, since I'd prefer a solid regular adjustable (USA made) with smooth action (and no gear lash) because they don't opening end drift either, and they do it without extra bulk on the handle (makes for better torquing if you need to). An okay tool, but doesn't do anything a good regular adjustable won't. My 2 cents... Sears still sells USA made adjustable on rack, in store. They have a little play, not super high end but loads better than china imports, and will probably get a variety more jobs done than this slightly bulky tool.
