Review on 🧲 MUTUACTOR 2Pack 100lb Anti-Scratch Neodymium Rubber Coated Magnet: Versatile Magnetic Base for Off-Road Vehicle Lighting, LED Working/Signal Lights, Antenna, and More! by Mike Ewing

I had some concerns that they might not be strong enough for my intended purpose. I wanted to mount LED panel lights to my overhead duct work, in my basement office, and they hold the ductwork like a champ, even with cables hanging from the lights.In fact, they are SO strong, that I caution to be careful with them. I accidentally put them back to back, and struggled to get them apart. I had to find a plastic tool, to split them apart.
