In our workshop (12 stages) we use, among other things this torque wrench and use this by complying with the conditions of each vehicle brand. So you can say that he is really used much. He now performs reliably for several years his ministry. The condition is impeccable, except that he has become a little rickety. The NM-setting can be adjusted really well only in increments of 10, but that's not a secret .. especially since the same company blue provides a slightly more expensive torque wrench in color ready with second closer scale.
For the price an absolute recommendation for all wrenches and even commercial use. Only on the accuracy and maintenance of this I can not say anything.
