Title: Wildly inaccurate, avoid it
Review: The calibration is off by a wild margin. I used this wrench it to install a cylinder head, and ended up almost blowing the engine. It was showing 11 ft lbs, but when I checked with another torque wrench, the torque was 16 ft lbs. I thought it is due to the torque being in the low range (this wrench is rated up to 80 ft lbs) so I gave it another chance. I used it to tighten a flywheel nut spec'ed at 33 ft lbs. I never got this wrench to click, while I tightened the nut almost as tight as I got it with an impact wrench! Bottom line: do not use this wrench if the job requires any accuracy at all!
