Like many I was looking for a reliable torque wrench but not shattered my wallet, so I searched ... searched ... to fall on it. The prior reviews are rather good and the prices more than reasonable I leaned on the characteristics (which remain similar with other keys to this price range) but the fact that it is certified by the TÜV (German Certification Body ) decided me.
In use now: very simple! clear instructions, with examples of torque, the key to good couple stops "screw" with a "click, click";) I did not check the reliability of the final torque but I tested on an aluminum swingarm, and the thread has not messed up.
