    Nothing Fancy. Plug and play it does its job and I've had no problems since installation. I would buy it again if necessary.

    Hard to fine, literally called a store that specializes in DIY (do it yourself) fixing technology and they had no idea what I was talking about and told me to check Home Depot. I needed this because of a "Hmmm" noise coming from a car sub woofer I installed in my home. The aux from this device is connected to my television, while the output is going to the cars audio amplifier. The ground wires from this device is also connected to the amplifier in the ground terminal. Problem fixed!

    I bought this isolator to eliminate noise from my auto stereo. It was really easy to install. When i installed it and turned on my stereo, the noise was still there so i thought it was junk. However, i found out later that the noise was from a loose wire so im giving this 3 stars because i dont really know if it works or not to eliminate the stereo noise. In regards to buying it, it was cheap and easy to order and pick up at the local best buy. Overall, it was an easy transaction

    Connecting the ground wires to ground made buzzing worse. But leaving the ground wires unhooked fixed my buzzing.
