Replaced my 2000 Honda Accord headlamps with LEDs and the buzzing would start when I would have the lights and AM radio on. These were a quick fix! And much cheaper than a new transformer!

Did NOT work on new fog lights no matter where I installed them, near the battery or near the lights, still have the same radio interference!

great to reduce interference from nearby electronics, especially things with electric motors. I put these on the power cables for my computer and audio visual equipment along with connection cables. I don't get any weird interference when the smoothy machine is running.

The magnets on the largest size are too big to allow the clips to shut. The rest works fine.

I bought the assortment pack to start addressing RFI issue in my home office. My major win was snapping a couple of the larger size ones on the AC cable for my C Crane CC Radio 3 that was getting interference on several AM station when running on AC. Two cores made a big difference. I used a smaller core on the power cable of an Emerson clock radio to clear up some RFI there as well. The rest of the assortment will be laying around in case other issues arise. Nice to have an assortment, since you never know what you might need.

I recently replaced most of the lamps in my jeep, with LEDs. I also added fog and offroad lights as well. (Also LEDs) I noticed when I was listening to the radio and I turned on the LED lights, the radio became "staticy", and sounded like it was too far away to get a signal. Turning off the LEDs, the station came right back.I knew ferrite collars would suppress RF interference, so I ordered this set. Made from the finest plastic and Chinese sourced ferrite (low carbon steel powder and ceramic powder) , I was skeptical, but intrigued at the price and packaging. (A nice assortment of sizes, for various wires and pairs) I added a collar at each lamp, using both wires when I could, or just the ground when i had room for only one.The results were amazing. Hats off to the child labor force who toil in the sweatshops, building these things for pennies a day! They solved the RF issues I was having. I'll be adding these to every pigtail in the system, where I replace an incandescent lamp with an LED.

These didn't work for us. They were easy to install, but the buzz is still there.
