The item has great potential, but it fealt poorly manufactured. It also would not accommodate my axcel driver with bridgelock mount.

Neat product. Used for setting 3rd axis. Seems to work. Results untested as of yet. Could use some type of clamp system to hold it secure to a table.

This tool is a shop favorite. It was difficult setting second and third axis while the sight was on the bow. This tool solved that problem.
