Review on ULIBERMAGNET Heavy Duty Neodymium Magnetic Coat Hooks For Metal And More - Strong And Versatile Hooks For Towels, Coats, Bags, And Umbrellas by Jason Yancy

The hook itself is lightweight, the magnet has a good weight. The strength of the magnet along with some friction of the rubber surrounding the magnet allows you to hang up quite heavy items (e.g. coats). The hook is likely made of aluminum. The diameter of the hook tube is about half an inch (just a tad smaller than a 1 cent coin).The hooks (2) arrive in a small box and just have to be screwed together and are ready to be used. Be careful not to put the magnets too close to credit cards, mobile phones, computers and other devices sensitive to magnetism.
