“One very nice surprise is the mounting clip. Not only does it take advantage of all three lugs on both sides, it is hinged on the tool side and proved very easy to use. Latch the first side down under the three lugs, insert a flat blade screwdriver into the capture, and just hinge the second side onto the lugs. One of the nicest socket mount clips I have ever used. Should become the standard, it is that good.”
