I am a little disappointed with my purchase. I already had a key 40 210 Nm and I needed a model that can trigger it below. I hesitated with other models, but there were too few and were limited square. So I chose this one which seemed versatile and with a square ". Unfortunately, it is not very accurate below 40 Nm and not it always fires. Even the setting is random before 40 Nm and did not brake screws. It's still usable, but we must be vigilant and not to blindly trust him ... If you need accuracy for low and tightening purposes, it is not for you ;-)
