These wonderful magnetic hooks are so very handy. The magnets are strong, so they stay put and I use them for all kinds of things. I have a metal desk in my office and down the legs are the metal magnets. When I am charging my Garmin Fit Bit or my iPhone, I lay the cords over the metal hooks so I am not tripping on the cords and they are nice and neat. When I finish charging my devices, the cord is conveniently there over the hook for next time. I also have metal doors in my office and I hang important tools from the hooks to grab them easily.
