DTECHSerial Adapter 3-Pack (DB9 F-F, M-F, M-M), Mini Size RS232 Coupler, Female to Male 9 Pin Connector, for PC Computer Data TransferClimatePartner certified

Im a service tech, and was going to use these if I had to connect to a device and my cable had the wrong end on it. I have used it for that. But what saved me was I connected a device to a transmitter, but the cable had the wrong end on it. I remembered I had these, and gave it to the customer to the job was able to be completed. Customer was very happy, and made the install quick, clean and most importantly, working!

Beware that any of the female-ended ones these cannot successfully change the gender of a cable to allow it to plug into a device - they will only work to join two cables together. As many (all other one-star) reviews have noted, these adapters are an assembly of pins which are held together by two standard-size nuts/bolts which will accept a cable's securing threads. These pins for assembly are essential to leave in place or this mini-adapter falls apart. Unfortunately when trying to plug a female adapter end into a male socket on any computing device, the two nuts on the mini-adapter prevent the two from actually connecting because the male socket on a computer has those same nuts - so close, and yet, so far. They were cheap enough that I'll keep around in case of cable connections, but I'll have to order something else to accomplish my task at hand.

worked as decribed

A little confusing at first to have a set of gender changes which includes one adapter which doesn't change the gender until you realize that with these 3 adapters you can also connect any 2 cables together regardless of gender. I was very disappointed that I could not remove the screws from the male to female gender changer (it is female on both sides) without the metal caps falling off. That makes it useless as a gender changer. It's only good for joining two cables because the screws on the adapter will butt up against the screws on the device I am trying to plug into, preventing it from plugging in. I actually had this issue trying to connect a USB to serial cable directly to a motor drive the other day. I'll have to see if I can find this one separately without this flaw.

Product was exactly as advetised

Works well, was quickly available. Should hold up well.

This product literally came apart when I attached it, plugged it into a serial port and then moved it to a different serial port on the same device. I threw it away.

Before trying to use the one adapter I bought this pack for it was obvious it wasn’t going to work because the two retaining screws (one on either side of the actual serial port) are the same gender as both the serial port on my device, and also the serial cable I need to use.I don’t know if I got a returned item that someone took apart and failed to reassemble, or if these are just garbage (I’ll say that the package didn’t appear to have been opened before) but before I could try the adapter anyway it just fell apart.Unfortunately for me I didn’t see the other reviews where other people had this exact same experience.
