... This is not quite unsound acting torque wrenches for hobby and private everyday work with sufficient accuracy all, but is only suitable for right-hand thread. That he - in particular larger torque range - is to adjust a little stiff, was already described, but whoever does not believe to have to be a "real man", can indeed attach the extension. And if that's not enough, is still 'nen 27er on 8-Kant - then get's even Omi slightly rotated. A pity, I find that there is no button to eject the inserted tool. Annoying is also that the locking screw from time to time unintentionally rotates: this is definitely nothing for the professional workshop ... it's just not a Hazet or Gedore ...
Who has to screw no space technology and does not need to adjust a lot, coming from hereby tired. The price is OK; and: remember to relax him after use - then the accuracy is maintained for longer!
