Review on 🔧 Steelman Pro Bluetooth ChassisEAR Auto Diagnostics Kit: Ultimate Electronic Stethoscope for Vibration & Noise Detection, with USB Bluetooth Dongle, Headphones & Software by Jake Atonyo

It completely worthless the obvious issues with Bluetooth connectivity and the complexity of setting up the instrument software to ignore . It barely works as a stethoscope anymore. I tested the tool on a desktop and there is no reason for the sensors picking up noise. The recording function only records the sound, not the graphic, the graphic is displayed channel by channel, so you cannot compare two readings at the same time. Even if the sensors could sometimes pick up the drop of a pin, sometimes they wouldn't hear the passing train. The dB values do not even correspond to what a noise should be. If anyone wants to try it I'll sell it for $50.
