Review on 🔑 Keyhole Companion: Effortless Keyhole Slot Fastener Location Marking Tool - Ideal for Walls, Cabinets, and More! by Luis Neels

At first I had some doubts about how this tool would work. Trying to hang lots of items with keyhole slots has always been very difficult. Well, all I can say is: WOW! I took the product out of the packaging to hang the extension in the store. It was literally as easy as 3 steps. I installed 2 tools on the back of the extension, tightened it and removed the ink caps. Install the extension in the desired location and press the extension against the wall. There are 2 clearly visible crosses on the wall where I put the screws in the wall. Then the extension installed exactly where I wanted. No measurements were required. AWESOME product!
