It works.
Compact size and works as expected.

It correctly transposes recv and xmit signals, unlike many other so-called null modems on Amazon
Worked perfectly, delivered quickly.

Bought several times, they are good
These are good and cheap. They've never not worked.

Very convenient, except that it's a 2-pack of the same thing
These are awesome. The screws can be removed without them falling apart so I can plug them directly into my cable and into the device I am connecting to. My only complaint is that they came in a 2-pack with the same genders. I don't need 2 of the same thing. 1 of each type would have been more useful to me. Male to male, female to female and male to female in one kit would have been perfect.

The slimline design minimizes strain on computer ports, and the gold-plated contacts ensure reliable connections even after repeated use . The removable and reversible screws add flexibility, making them compatible with various setups. Whether you're connecting legacy hardware or setting up a console interface, these adapters perform flawlessly. Highly recommended

The Most Compact n/m Adapter
These adapters (as sold by dgjiachen) conform to the "Full Handshaking" pinout described on Wikipedia (search for "Null modem"), so by-and-large will work with normal serial ports without any special settings. I have used one to connect a PL2303-based USB serial adapter to the serial port of a server so that I can do some startup troubleshooting via the console. Took advantage of the twin pack, as one shall inevitably go walkies when surrounded by envious techies curious about how I make fixes as close to the metal as possible...

Keep one with your usb-DB9 adapter
There are lots of serial devices wired to expect a modem connection, including most usb-db9 adapters. This is just what was needed for programming up my firewalls
