The adapter works right out of the box in Windows 10. Had to install Parallax driver in XP (FTDI drivers didn't work). I use for my job to connect to old PLC and I find much more reliable than any Prolofic based adapter... Just wished there was a case of some kind to protect it when I carry it in my bag.

Solid product
Worked on both Win10 & Raspbian without installing any driver. Doesn't come with a hard case but is not a concern in my project.
