### ⭐⭐⭐⭐⭐ Works without trouble
*by J***N on April 19, 2025*

These usb to serial converters are often finicky. This one just worked immediately. Nice.

### ⭐⭐⭐⭐⭐ Took a few minutes for all the drivers to settle down and work.
*by J***N on April 16, 2023*

I got this particular maker since it was rated as being very compatible. And after waiting a few minutes for Windows 11 to correctly load up all the drivers for Com3 to appear; it does indeed work without fail. Nice clean signaling and now works without fail. Sure, I may make a mistake; but at least I don't have to worry about the communication.
