Since I wouldn't travel without a complete socket set, this adds nothing to my tool kit. It isn't as long as a 1/2" flex handle or torque wrench I carry. The tool's length is 20.75", so it's maximum leverage is less than a 20" X lug wrench. In a car with limited storage it might be useful, but in an RV I can carry better tools.
Interesting that in the two different listings for this tool, at Home Depot or Amazon, neither list the socket sizes. Amazon does say, "Two double-sided lug nut sockets to fit virtually every passenger vehicle on the road today." But it doesn't specify whether 6 point or 12 point sockets, metric or SAE.
