Review on 🔧 MESTUDIO Cabinet Hardware Jig - Adjustable Punch Locator Drill Guide for Handle Installation, Knobs, and Drawer Pulls on Doors and Drawers. Includes Center Punch for Enhanced Precision. by Corey Kim

Putting on some gear in a hurry was awful. BUT the flat plastic edges are not perfectly straight and have caused slight misalignment in the hardware. If they replaced the plastic with aluminum or something, that would be pretty decent. There's also no easy way to mark the center of the pattern with it, meaning I had to measure the whole thing with a tape measure and transfer the line to the center and top of the drawer/door, which I had to "aim" at for the center of the leader.
