First off, let me say this tool is a lifesaver for anyone dealing with squeaky or misaligned doors. The dual-head design is genius—one side fits 14-18mm hinges, the other 23-25mm, covering most standard door types. I used it on my stubborn fireproof door that wouldn’t close properly, and after a few twists, it was back to smooth operation.

The carbon steel construction feels sturdy in hand, and it didn’t bend or warp during use. However, be cautious—the sharp edges mentioned in one review are real. I accidentally scratched a hinge while adjusting (oops!). A little masking tape on the hinge edge solves this issue easily though.

Where it shines: adjusting flag hinges on security doors. The leverage makes it effortless compared to pliers or hammers. But fair warning—it’s not magic. For severely bent hinges or complex alignment issues, you might still need professional help.

Pro tip: Keep this in your toolbox even if your doors seem fine now. When that inevitable door-drooping moment comes (and it will), you’ll be grateful to have this $15 problem-solver ready to go.
