10.6inch Battery TV, Support/car... vs XtremPro Hi-end Ground Loop Nois...

This works great in my fish house. It also chills fidgety grandkids out.

Worked like a champ. Zero noise. This definitely fixes ground loops.

Best regards daniel alvarez. Very nice, easy install. I was so frustrated by my problem this product solved it right away.

Like all transformer type couplers, these work extremely well at ending ground loop problems. Metal housing even offers shielding. It’s legit and has what seems to be decent transformers inside.

Same whining ground loop noise with or without.
