Works with Microsoft Windows 10 connected to USB 3.2 generation laptop ports. The BAFX version of this gauge is older in my experience BAFX gauges only work on Microsoft Windows 10 (or earlier versions of Microsoft Windows) with USB 2 ports. I have a lot of experience with older/earlier BAFX hardware, but this newer hardware has changed the button layout and added more recording features. both software and hardware, which makes things a bit more confusing. Also, the power button didn't turn the unit off at first, so the batteries had to be removed. Robust device from China.
