Review on 🎛️ Backlight 30-130DB Professional Instrument Calibrator by Brandon Patterson

This is my first decibel meter, I wasn't quite sure how to use it. I contacted support via email, they sent me a video tutorial and explained how to use it. Excellent customer service! Highly recommended. I have used the meter successfully in both professional and environmental settings. Works as stated in the instructions. Was well packed. Data is collected by accurate, easy-to-use software. you can stay all night No problem!
