Unfortunately it did not work at all for me. But after further research, it turned out that there was some bad capacitors in my subwoofer.
To be fair, perhaps I don't have the greated understanding of this product and its uses. I expected it to stop my home stereo subwoffer from humming that seems to be caused by a ground loop from the research I have done, but it litterly had zero effect when I plugged it in.
I took it to a local repair shop and my issue was that there was some bad capacitor’s so I cannot recommend or not recommend this product and I don’t see a way to delete my review so I wanted to update this. Bottom line is unless you really know what you doing you may want to consult with a repair shop if you’re issue was similar to mine.
Lacks the tabs to properly fit and creates a noise due to air gaps. Waste of money in my opinion. I will have to buy the filter with the plastic tabs on the side to fix this.
