Review on 🔌 Install Bay IBR68: The Ultimate All In One Tester - Retail Pack (Black) by Jose Ballard

It arrived quickly, was well packaged and even came with a 9v battery. I wanted this because it's the same type that was used , when I was working in a car radio shop . It's easy to use, lightweight, and has instructions on the back for those who have never used it. I have already successfully checked the polarity of the loudspeakers and used the frequency generator function. Make no mistake with this Install Bay tester. It is required for home and car audio systems. Thanks.
