Review on 🔒 Yarachel 50PCS RFI EMI Noise Suppressor Cable Clip - Ideal for 3.5mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter Cable by Anthony Heinrichs

My husband and I use DVRs in our cars when we drive. We also like to make music. I mostly use an MP3 player while my husband uses the radio in his car. He recently bought a "new" used car to replace another. He is a delivery driver and spends a lot of time in his car. To his dismay the radio picked up no signal at all when the DVR was on! After doing some research on the issue, I bought these RFI EMI interference suppression cable clamps (aka ferrite beads) and placed one on each end of the DVR cable, about 2 inches from the connectors. It worked! My husband is a happy man! Now he has both the radio and the DVR working at the same time.
