It's fine for its price.....a thousandth of a gap that I read, I laugh......I don't have it, but even if I did, would you be able to catch it with this 1mm key ???

Generally, the tools of this particular company are not suitable for professional use. As soon as you close this specific wrench on the bolt, it becomes difficult to remove it. With the jaws fully closed in the front and the tips touching the inner part, there is an opening of about one millimeter. They do not fit properly. I have purchased other tools from this company with problems and flaws. Friend jimm spiliot, to make it a bit clearer for you, if you try to grip a 24mm bolt, for example, you will have to leave about 1mm for the wrench to rotate, plus the approximately 1.5mm gap that this specific tool has at the back, and the French tool has about 3mm gap. If you apply force and the French tool slips, you will have an unpleasant surprise for your fingers, and that's when you will stop laughing.
