How about a rundown on how it works. It's still more expensive than the Ebay Segway Leveler, which is probably the best deal for the buck. I didn't say it was the best leveler, just the most leveler for the money, at $20.

Sorry I didn't see this sooner.
The tool uses two Vee blocks. One Vee block is set against the objective bell of the scope. The other block is slid down until it locates against the rifle barrel. Then you use the bubble level to level the action/scope which places the scope and rifle centered in the vertical plane. The body of the tool has a slot milled through it (window) which allows you to line up the vertical crosshair with an external reference (plumb line). You then level your ACD and it's good to go.
