Review: Works perfect on Windows 10 64 bit-Plug and Play - I liked that Windows 10 recognized it instantly and loaded drivers for it, the disc was not necessary. This adapter is mechanically exactly the same as the COM connector that is found on the XP and older computers. I plugged my radio programming cable into it and the computer found it in 2 seconds. Communication to and from the radio was faultless. I don't know why other reviewers are complaining about the female threaded studs, perhaps they don't know what a proper COM jack is supposed to look like? I did notice some other devices similar to this one that have the correct male pins but have the hold down bolts of a female plug instead of the nuts found on a jack, but those by definition are not standard COM jacks, but are instead a mechanical corruption of the original concept. I find nothing to dislike with this device other than perhaps it could use a bit longer wire.
Review: Great little tool - A very useful device. Incredibly tolerant of everything I have subjected it to. Worked flawlessly with the drivers included (on a 7cm CDROM) on Windows XP and XP Pro. Ubuntu recognized it with native drivers. Works with arbitrary baud rates correctly under Windows but Linux takes a bit more work. On Ubuntu it does work correctly with standard 16550 UART speeds right out of the box. Neatly assembled and sturdy for its size. Good quality receptacles on both ends (USB and DB9). Recommended for the price.

### ⭐⭐⭐⭐ Works great, easy install with Windows 7, Not with Windows 10
*by J***R on December 2, 2020*

I struggled with this usb serial adapter for hours with Windows 10. Used the included disc with drivers. Never could get it to work. However, with windows 7, it was easy. Plug and play took 10-15 minutes. Did not need driver disc. Then it worked like a charm. I was able to download and install new firmware for my ioptron telescope mount.
