There seems to be at least 2-3 different ways to assemble this thing, but it works great once you assemble it. Nuts on the same wheel with a Milwaukee 1/2 18v impact wrench, it was able to snap the nuts off with a bit of the force I was expecting. Disassembles well and packs into a gear bag (24" rothco duffel bag) which I also use to store/carry off-road emergency gear. It takes a lot less grunting than a regular spider and a lot better than the OEM tool that comes with it most cars that still contain a spare part.
