A lot of shops [4x4] now use these tools and when I get my wheels rotated I always ask them to use the torque ends.
that way if out wheeling I can undo the wheel nuts myself. But for general use if you can get to the nut or bolt very handy.
For tyres I still use my 12v Kangaroo creek impact wrench, slow but works for me. rotating 4 tyres is 20mins faster
