Solid and reliable unit, good for industrial applications
I've used a dozen or so of these over the years, for machine serial communications. No failures, easy setup. The driver includes a few settings that ensure wide compatibility, including assignment of the port number and port latency, among others. I have installed it on laptops, desktops, and Intel NUC PCs, running Windows 7 and 10.
