Review on KAIFNT K552 Digital Torque Adapter: 3/8-Inch 5 to 100 ft·lbs, Buzzer/LED Flash Notification - Dual Direction by Ken Booker

I bought this to check the calibration of the Harbor Freight click torque wrench. Both were only a few pounds apart, which I took as a good sign. It's easy to use and unlike other battery powered torque wrenches I've used, this one uses larger batteries which means it won't run out of battery power. (This shouldn't be a problem, so I'm not sure why other products use tiny batteries that only tighten one eyelet.) Anyway, if you've tried other digital torque wrenches and had the same experience as me , then I recommend this one. Works well, the battery does not die. I've played around with this for a while to get familiar with all the settings and once I've figured out everything I have to say this little object is a fantastic addition to my toolbox. I am very pleased!
