Amazing! I really had my doubts about this product actually working. My problem was that I have a studio space in a loft above the garage. Anything that was plugged in or turned on downstairs would put a ton of static on my radio stations, making it impossible to hear what was being said or played. It was driving me totally nuts when people would come in and turn the lights on in the garage bays. Nothing I was doing would help, no matter what the position or height of the antenna. Apparently, there was enough "bleed" from the electrical lines on the 1st level that were on the same frequency as my radio (or something like that, it was explained to me but I don't remember the details.) So, I ordered these, I split my electrical cord and put one on each side of it, then put three on the antenna wire at 1 foot increments. Results? TOTALLY CLEAN SIGNAL, ZERO STATIC! Fantastic! I am one very happy customer. Thank you so much!

A Lifespan TR1200 treadmill and a Visio Tv. As soon as I stepped on the treadmill and pressed start, the Tv froze into pixelation. I tried separate surge protectors, no help. I put 5 of these on the Treadmill power cord and 5 on the TV power cord. And it actually helped quite a bit! Still an ocassional freeze up(especially in very humid weather) but a big improvement in my setup. It’s pretty low expense, so worth a try.

I bought this because my 2 big living-room speakers (connected to TV audio) have some white noise, like soft low-level static almost, that's always present, even when the TV's turned off. I connected a couple of these to the speaker-wire, and it had zero effect. I even combined this product with using another similar noise-reduction item , the BESIGN Ground Loop Noise Isolator (ASIN B06XQYN77L )and still nothing - not one single improvement! So I guess I wasted my money.

For smaller wires. Easy to use. Works well.

What can I say don’t expect too much from it.

I have a 1997 Mazda Protege DX with an aftermarket radio in it, I'm restoring it because it was my mother-in-law's car and she passed away about a year ago and I'm going to restore it and give it to one of the kids,, that being said I installed some hid LED headlights with a ballast after I did that I could pretty much only pick up a couple of radio stations because of all the static when the lights were on. I did some research on ferrite and saw this product which I have now purchased and as soon as I installed them on the lines between the LED ballast in the Headlights about 90% of the static left and I was able to receive my radio stations. I have since purchased more ferrite and installed these on my radio antenna and also on the lines coming out of my alternator, and they seem to do a pretty fair job of reducing that static noise that you get in some vehicles on the radio when your turn signals are blinking on and off and so forth if you're having a problem like this I think they're worth giving a try.

Great price and quality
