This is a General branded product and will likely do what it was designed to do for many years. The reason I made the note is because the metal is much thinner than other drill jigs. Probably my other sensors were thicker than they should have been, but they certainly gave the user a consistent feel. To be honest, $12.99 seems a few bucks more for this version. I will keep and use it and one day I will look for another version.
