This item really helped my front door not banging into my new window. Genius.

Excellent

This is a handy device that keeps a hallway door from hitting the grandfather clock beside it when the door is swung open too far. We also have one on the lower hinge. The hinge pin stop has made a small indentation in the wooden door frame, but it isn't noticeable, and I'd rather the dent be there than in the clock cabinet. It is doing its job, and I would buy these again.
