I purchased these with the hopes of blocking HF RF noise from my Wi-Fi and other computing devices. It didn’t seem to have any impact. It would be useful if the vendor would let us know the ferrite mix so we can determine if it’ll block the appropriate frequency range or not

After completing a LED light installation on my truck and then noticing some EFI 'noise' on the vehicle radio, I ordered this ferrite bead pack. Two were installed on the power leads to each LED light system which cleared up the noise heard on the radio. With that success, I put a small one on the antenna wire of a small radio in the garage. I had changed out the light bulbs in the garage with LED bulbs and they interfered with the garage radio. After the ferrite bead on the antenna wire, problem is gone. I read some other reviews about the plastic clip breaking but I found no issues if some care is given
