Astro Pneumatic 3/8" Flexible Extension Bar is designed to provide access hard to reach areas and awkward socket placements. It is constructed from high quality chrome vanadium steel and offers long lasting durability. This bar is sturdy and is easy as well as convenient to use.
Work fine and as expected, the main advantage of this tool is that you can use it to screw both ways! not the case with simple spring design like cheaper product. Price is cheap for was you get! outer spring is just for protection of inside 'assemble' links. These links make this tool to work both ways.
