I had a particular need for strong magnets that can be attached to the bottom of the audio device to keep them from sliding onto other audio devices (I have stacked components on top of each other). These magnets worked great - a countersunk hole in the center of the magnet made it easy to screw into the underside of the existing component feet - and the magnets held the components securely together. The only problem was getting the magnets off of each one. and keep them separate on my workbench (like I said, they're STRONG! - and will seek each other out!)
