Review on Adjustable Punch Locator Drill Template Guide - Cabinet Hardware Jig Tool, Wood Drilling Dowelling Guide for Installing Handles Knobs on Doors and Drawers by Bryan Ramirez

After checking a closet door, I noticed that the handle was not vertical. After checking and rechecking my measurements with the tool, I found that the longer plastic splint was warped about 2mm square from end to end. This caused my holes to deviate from that edge. Luckily I tested this on a closet door that was going to be filled and painted, so it wasn't a huge loss. I recommend a solid jig or a precision quality jig that doesn't deform as easily as plastic.
