Review on 🔒 Stardrift 10-Pack 11mm Black Snap-On Ferrite Core Bead Choke Ring Cord RFI EMI Noise Suppressor Filter - Ideal for HDMI DVI VGA Cable by Dmitriy Kingsley

I have a police handheld scanner that requires a line filter when plugged into my car's USB port due to signal loss due to noise. Cables with built-in ferrite cores are either expensive or bulky. I bought these to use my existing cable. I didn't want a set of 10 but the price was so low I bought them. DVD recorder, FPV glasses, drone and power supply units for my Raspberry Pi. Approx. 80 cents each additional protection against possible noise.
