The keys are surprisingly easy and very precisely. The ring part is not only angled as cheap keys, but slightly beheaded and then (less) angled. That leaves you can not easily hang on parts around the screw or nut to be solved.
The keys are a little longer than my old 08/15 fork wrench. Depending on the space ratio can be a disadvantage, but one can thus raise significantly more torque.
The key geometry is shaped such that it really aufbekommt the screws and the hex head not turning around.
The fact that they are forged and therefore unlike cheap molded keys on load not just break, aligns itself with the manufacturers themselves.
My conclusion: This key buys you only once in a lifetime. And from the point is also true of the price.
