Review on 🎛️ Backlight 30-130DB Professional Instrument Calibrator by Nick Cleary

Unfortunately, no matter how you set it up, the datalogging interface and the datalogging itself is utter garbage. In fact, when connected to a computer, the dB meter inexplicably showed 10 dB more. The supplied CD is a mini disc. So if, like most people, you only have a side-loading or front-loading player, it's useless. On the plus side, customer service was responsive and very pleasant. They really wanted to help and fix the situation. They sent me a software download so I could set up data logging. I may have just received a bad gauge, but I think it's quite a few design flaws that made it useless to me, which is why I sent it back.
