ANMBEST2PCS DB9 Solderless Connector, RS232 D-SUB Serial to 9-Pin Port Terminal Female Adapter Connector Breakout Board with Locking Housing

These connectors make if very easy to wire up and later change configurations of the wiring. They work well for my application. The screw terminals make them a little larger so if you have small spaces you need to plug into you may need to take that into consideration, but they are easy to use and eliminate the need to solder or de-solder if you make a mistake with wiring.

Used for intended purpose and it worked well

It was very easy to put together and was very sturdy.

They are really practical

The pin numbers and GND silkscreen on the board were very helpful keeping track of which wire goes where. In my application Roboteq HDC-2460 motor controller I was unable to use the 25 pin and 9 pin connectors side by side with the shells on due to the narrow spacing between connectors. I was able to use them by removing both backshells.

I love these breakouts. They're really well made. I had no issues with torqueing anything down. In the past, I've dealt with stripped, cross threaded screws on things like this but no problems here. I also like that they come with various sizes of bushings/clamps to accommodate different #'s and thicknesses of wires.

Everything you need to make a fully functional DB9, in my case for custom loopback connectors.

I have used a bunch of these and they are all fine. Easy to assemble. They smell pretty bad though coming out of the packaging.
