GEARWRENCH 85195 Flex 3/8" Electronic Torque Wrench

The Torque Wrench was easy to use and the fact that it measures angularity in addition to torque was a plus. I was excited to finally step up to digital, but quickly disappointed after damaging an engine block..The wrench was erratic, often turning off in the middle of bolt torque. I was using the wrench to torque cam shaft cover bolts to 14 nm and ended up over torquing and stripping threads in the engine cylinder head due to the fact that it never indicated target torque. This will result in either costly (if I take the car to the shop) or extremely time consuming rework as I will have to completely disassemble to tap and Heli-Coil the damaged engine cylinder head.I can't trust the one I received and will stick with my click torque wrenches. The accuracy on the included calibration sheet was also slightly less than advertised on Amazon's site.
