Did a great job. Had my outdoor antenna connected to my police scanner which is hooked up to my sound system. I was getting a loud hum and this took about 95% of the hum out. In my book, that's a winner.

I connected it to a Bluetooth receiver that had noise due to charging. This product reduced the noise almost entirely. The problem is that it also cuts some audio frequencies, bass for example sounds distorted. I used it for about an hour and realized I prefer the charging noise.

Very good item does the job its supposed to. It's also nice because it is small it doesn't get in the way.

I bought this for my 07 lexus is350 after I bought the besign bk01 bluetooth adapter without the ground loop isolator. I bought this separate because my car needed it. Radio sounds great now!
