I have the 10 inch version. I love them. They won't make a Crescent wrench obsolete, but I'd rather carry these in my tool bag than a 12 inch adjustable. You can tighten a 3/4" wedge anchor with a 15/16" nut to 90ft-lbs with the Knipex, so it's very capable. I would definitely say they are more suited for low(er) torque jobs not requiring you to do chin ups on the wrench. If you need two hands and your body weight to move a fastener, get a big adjustable.
