Exactly what I needed and easy to use
It arrived fast, was packaged well, and even came with a 9v battery. I wanted it because it is the same kind that was used when I worked at a car audio shop. It's simple to use, lightweight, and has instructions on the back for those who never used one. I've already successfully tested speaker polarity and used the frequency generator function. Can't go wrong with this Install Bay tester. It's essential for home and car audio. Thank you.
