Very good quality for this key! A little big but it exudes quality, easy adjusting knob, already had this kind of key in use pro! Only downside was 40 until she begins 200. Forced to take the small clamp for small :-(
Step back because I've used it once or twice. I can not comment on the accuracy of the tool since no comparison. In any case, it does not "cheap". I do not vouais a first prize that goes awry after a month or 300 euros put into a high-end wrench
