Personally, I have only positive emotions when working with this tool. -Fixation of fenders, where the key cannot turn around . and the stud at the anchor got out beyond the already deep head for the wrench) - Tighten the nuts on the studs near the metal trays (and according to the law of meanness there is a "P"-shaped profile where an ordinary wrench can maneuver 1-2 cm. The length of the stud can go far beyond the depth of the head)) The set is highly specialized - but in rare moments you will be very glad that you bought it)
